Updates github/codeql-action from 4.38.0 to 4.38.1

Release notes

Sourced from github/codeql-action's releases.

v4.38.1

• The CodeQL Action now has experimental support for CodeQL releases for which per-language bundles are available. Per-language bundles support analysis for a single language and are therefore smaller than the combined bundles that allow analysis for all supported languages. As a result, per-language bundles take up less space on disk and are faster to download. We expect to roll this change out to everyone in the coming weeks. #4146
