chore: bump version to 2.22.5

Version bump to trigger automated release workflow and verify that the
YAML syntax fix (commit 79ef853) works correctly.

Previous release attempt for 2.22.4 failed due to YAML syntax error
(emoji in heredoc). This version bump will test the complete release
pipeline end-to-end.
