Lint action missing errors on PRs

[kate-osborn]

Describe the bug
The lint action passed on the PR but failed on the merge to main.

PR run: https://github.com/nginxinc/nginx-gateway-fabric/actions/runs/6499218551
Merge to main run: https://github.com/nginxinc/nginx-gateway-fabric/actions/runs/6499802831/job/17654089998

The pre-commit hook also missed this error.

Expected behavior

• All lint errors should be caught before merging a PR to main.
• Pre-commit hook should catch all lint errors
