Upgrade compile-testing 0.21.0 -> 0.23.0

This way `error_prone_test_helpers`'s runtime classpath includes
`auto-value-annotations` instead of `auto-value`.

See:
- https://github.com/google/compile-testing/releases/tag/v0.22.0
- https://github.com/google/compile-testing/releases/tag/v0.23.0
- google/compile-testing@v0.21.0...v0.23.0
