Miscellaneous repository updates

[sayomaki]

• Add documentation compile check to CI, as mentioned in fixing unicode errors in build: more fixes needed #1701 Completed in fixing unicode errors in build: more fixes needed #1701
• Fix pull request template not working (add template similar the format in the frontend repo)
• Reduce the pre-push hook run time (removed building and testing of code, as we have the CI to do that now) and instead only check format & linting.
• Remove pre-commit hook as it is handled by the pre-push hook already. For users who are looking to keep their code well-formatted during coding, the use of IDE provided features will suffice.
