Refactor GitHub Actions workflows

-  Remove unnecessary lines in deploy.yml
-  Rename `validate-pr` job to `validate-labels` in pr_lint.yml and add concurrency settings
-  Modify the way of getting pull request data in pr_lint.yml
-  Add `validate-code`, `validate-docker-build`, and `validate-branch` jobs in pr_lint.yml with proper concurrency settings
-  In `validate-docker-build`, implement Docker image building and caching
-  Check branch name with version in `validate-branch` job
