Documentation updates for RAPIDS for Apache Spark -> NVIDIA cuDF plugin for Apache Spark rename

[sameerz]

Contributes to #15107

Description

The https://github.com/nvidia/spark-rapids repository has been renamed to https://github.com/nvidia/cudf-spark. This PR rolls out name changes for content and links referenced in the documentation.

Not changed here are documentation updates for configurations. Configurations will be added to support the new product name (removing rapids) with a deprecation period. Documentation for configurations can be updated when new configuration names are enabled.

Note that this PR modifies some generated documentation, so pre-merge CI should be enabled.

Thanks @sameerz

The docs site chrome still advertises the old product/repo: docs/_config.yml (line 21) has aux-link labels for “RAPIDS Accelerator for Apache Spark” and links the plugin to github.com/nvidia/spark-rapids. For a rename PR, that visible navigation should probably become cuDF for Spark / cudf-spark.

A few polish issues: git diff --check reports trailing whitespace in README.md, docs/download.md, docs/dev/mem_debug.md, and docs/supported_ops.md.

Thanks for the review.

Removed extraneous spaces

For the docs site chrome / User Guide route: I drafted the companion docs MR to move the published user guide route to the new product path in documentation repo: MR179

I also requested the docs owner to update the Docs Hub routing. Until that route is live, links under https://docs.nvidia.com/cudf-spark/user-guide/... may still 404

MR179 is still also under review

[sameerz]

We can do a follow up PR once MR179 is merged. This change will roll out during the course of 26.08.

There are still a few visible naming inconsistencies between cuDF for Apache Spark and cuDF for Spark in the updated docs. If the official product name for this PR is cuDF for Apache Spark, these should be aligned:

• README.md: the title says cuDF for Apache Spark, but the note says cuDF for Spark was formerly known... and the project name is cuDF for Spark.
• docs/download.md: the intro link text says cuDF for Apache Spark, but later says cuDF for Spark requires..., classpath ... uses cuDF for Spark, and cuDF Spark consists....
• docs/_config.yml: both aux link labels say cuDF for Apache Spark, which is different from the shorter cuDF for Spark wording used elsewhere.
• Generated docs/config text also mixes both forms, e.g. docs/configs.md, docs/additional-functionality/advanced_configs.md, docs/supported_ops.md, and their source strings in RapidsConf.scala / TypeChecks.scala.

* `README.md`: the title says `cuDF for Apache Spark`, but the note says `cuDF for Spark was formerly known...` and `the project name is cuDF for Spark`.

Thanks for the feedback. The first instance of referring to the product requires us to use the Apache Spark full name per the guidelines. Following mentions can use Spark. That's the rationale for the naming.

Greptile Summary

This PR is a broad documentation rename rolling out the rebranding of "RAPIDS Accelerator for Apache Spark" to "NVIDIA cuDF plugin for Apache Spark" across 43 files, in parallel with the GitHub repository rename from NVIDIA/spark-rapids to NVIDIA/cudf-spark.

• All GitHub issue/PR/discussion links and repository SCM metadata in pom.xml are updated to point at NVIDIA/cudf-spark; artifact IDs and Maven coordinates are intentionally left unchanged per the PR description.
• Configuration documentation strings in RapidsConf.scala and operator-support tables in TypeChecks.scala are updated to use the new product name; all docs.nvidia.com/spark-rapids/... user-guide URLs are intentionally left unchanged, as those are managed by NVIDIA's external docs team and require a separate migration.

Confidence Score: 5/5

Safe to merge — all changes are documentation text and Maven metadata with no impact on plugin runtime behavior.

Every changed line is either a product name string, a GitHub URL swap (spark-rapids → cudf-spark), or Maven project metadata. No functional Scala code paths, no GPU operator logic, no configuration key names, and no artifact coordinates are altered. The docs.nvidia.com user-guide URLs are intentionally left unchanged pending a separate external-docs migration, which is consistent throughout the PR.

Files Needing Attention: No files require special attention.

Important Files Changed

Nit: The deepwiki page still says RAPIDS Accelerator for Apache Spark. Are we able to update it accordingly?

[sameerz]

Once we rename the link it should trigger a rebuild of the deepwiki page. Let's see if it works.
