With the recent bump of golangci-linter version from 2.1.6 to 2.3.1, Under the revive linter, a certain rule - avoid meaningless package names has been skipped to allow the version update through #2457.

To fix this issue, one may need to remove the 'var-naming: avoid meaningless package names - rule under exclusions from the .golangci.yml file from the repository root and run the linter locally with make lint command. Please make appropriate changes to suppress the issue.
