fix: update supporters path resolution and clear linter warnings

WHY:
After flattening the software directory, the Community Partners banner on the homepage lost its images because `data/supporters.toml` was still trying to look up page bundles using the old physical paths. Additionally, the new Node.js validation script was triggering false-positive errors in JSHint.

GOAL:
1. Update `data/supporters.toml` to point `page_path` values to the new flattened software directories, restoring `site.GetPage` bundle lookups.
2. Add JSHint node environment pragmas and strict-mode declarations to `scripts/validateContentTaxonomy.js` to satisfy IDE linters.
