[WIP] Prek in replacement of pre-commit

[acolombier]

This is a test to assert the situation with prek, which claim better results than pre-commit and is now widely adopted

For reference, the avg runtime for pre-commit is 4m41.

First run was lightning fast! 27s with cold cache
Second run was unbelievably slow, tho also operating on cold cache apparently: 6m42s

Looking at debug logs, hook install are all done within seconds but on the second run, qsscheck has taken 6m22 to install, without much details as of why it was this slow.

It could be related to a slowly performing pip install (bandwidth?). Will retry a few time

Turned out this was expected and is the result of qml_formater, which has been removed in 2.7/main

@mixxxdj/developers should we test that in main and see if we see better results? (CI runtime)
