php-oss-for-azure

Update Azure PHP monorepo package changelogs from `Unreleased` to concrete release versions and produce the exact `git tag` / `git push origin <tag>` command sequence for releasing those packages. Use when Codex is asked to plan or prepare a release for `/src/Identity`, `/src/Storage/*`, or `docs/`, especially when it must infer or apply version bumps, use prefixed monorepo tags, and avoid re-reading GitHub Actions for release conventions.
