chore: remove remaining CircleCI references after migration to GHA

- README.md: drop dead CircleCI status badge
- .golangci.yml: drop .circleci from exclude paths (directory was removed in #1784)
- test/packer_oci_example_test.go: remove CIRCLECI env var skip and now-unused os import
- test/azure/*.go (26 files): drop 'azure not set up for CircleCI' note (Azure tests now run via azure-tests.yml)

Linear: OSS-3396
