Pull request overview

This pull request upgrades GitHub Actions versions across the CI/CD workflow files. The changes update actions/checkout from v4 to v5, actions/setup-dotnet from v4 to v5, and stefanzweifel/git-auto-commit-action from v5 to v7. Additionally, it refines conditional logic in the CI workflow to properly scope test coverage and result uploads to only the C# build matrix entries, and removes persist-credentials: false from the publish job's checkout step to enable automated commits using a custom token.

• Updated core GitHub Actions (actions/checkout, actions/setup-dotnet) to their latest major versions
• Added matrix.language == 'csharp' condition to test coverage and upload steps to avoid redundant operations for non-C# matrix entries
• Removed persist-credentials: false in the publish job to allow git-auto-commit-action to function correctly

Inconsistent action version: actions/setup-dotnet@v2 should be updated to @v5 to match the upgrades in CI.yml (lines 38, 111, 158, 306). This ensures consistency across all workflow files and provides the latest features and fixes.
