ci: enable commit checker in github action

[WadeZhouRiema]

Enable commit checker in github action. Commit message should be like "feat: xxx", "ci: xxx", "fix: xxx", etc. Otherwise the github action will fail.

I found a better approach to the commitlint:

npx commitlint --from=main --extends @commitlint/config-conventional -V

It means:

• --from=main: Fetch the commit messages from branch main to this branch
• --extends: Specifying the standards and rules without giving a configuration file
• -V: Verbose mode to display how many commit messages are checked

So we could simply extend our make ci with:

.PHONY: ci
ci:
    # The existing rules here...
    # Install the dependencies...
    npm i -g @commitlint/{cli,config-conventional}
    npx commitlint --from=main --extends @commitlint/config-conventional -V

Since for most of the time our CI is triggered on PRs into the main branch, and locally we could run the same command for dry-runs.

Closing this PR for a better approach.
