Bruno Borges 513edc4f87 feat: expose cache-primary-key output (#597) [v5 backport] (#1089)
* feat: expose cache-primary-key output (#597)

Backport of the cache-primary-key output to the v5 release line.

Expose the primary cache key computed by the caching logic as a new
`cache-primary-key` action output, so workflows can compose the built-in
setup-java cache key with actions/cache or actions/cache/restore across
steps and dependent jobs.

- src/cache.ts: set the `cache-primary-key` output in restore()
- action.yml: declare the new output
- README.md: document the new output
- __tests__/cache.test.ts: assert the output is set
- dist: rebuild (CommonJS)

* Apply PR #1088 review suggestions to v5 backport

Port the review feedback from the main-line PR (#1088) into the v5 backport:
- src/cache.ts: use the STATE_CACHE_PRIMARY_KEY constant for the output name
  instead of a duplicated string literal
- action.yml / README.md: clarify that the output is also empty when caching
  is skipped (e.g. the cache service is unavailable)
- dist: rebuild
