DEV: Replace Overcommit with Lefthook (#7826)

Overcommit uses prebuilt hooks and require global installation.
To avoid this issues replace it with Lefthook.
Lefthook will be installed with npm packages. New contributors
will have fully consistent git hooks.

-# Use this file to configure the Overcommit hooks you wish to use. This will

-# At the topmost level of this YAML file is a key representing type of hook
-# being run (e.g. pre-commit, commit-msg, etc.). Within each type you can
-# customize each hook, such as whether to only run it on certain files (via
-# `include`), whether to only display output if it fails (via `quiet`), etc.
