feat: Skip lint when merging remote branch

[singara-velan]

Description

When merging a remote branch (origin/master) directly into the local branch (feature/branch-abc), the default git commits message will be "Merge remote-tracking branch 'origin/master' into feature/branch-abc".

Current lint doesn't cover this use case, so the commit message format is validated against the conventional commit standards and getting blocked.

This PR includes a regex to skip the git merge default commit message from linting.
