[FIX] config: fix pre-commit structure

The new pre-commit step added in cb1076b7 was executing bash
instructions regardless of the ENV variable `HUSKY_PRE_COMMIT` which
allows users to bypass the pre-commit altogether.
This prevents Windows Platform users from commiting altogether as the
instructions are not recognized.
