[v2] Custom pre-commit hook

[Alph3ga]

Added a custom pre-commit hook for linting commits, along with a shell script to install the hook.
Chose to do this over using the pre-commit tool because dependencies and runtime environments for all the hooks needed were externally managed anyway. This way, fewer things to look for if something breaks.

Yeah, rest of it looks decent enough. It will get the job done.

If you somehow want it to be more robust then add checks whether those commands ran properly or not and print corresponding messages

LGTM

@proffapt merge if the shell script is fine.

Ahhh, my base standard for shell scripts is a bit high, not fine but will get the job done so fine.. idk
