pre-commit: add hooks for spell and lint

Added pre-commit hooks for spell and lint as described in #52 (closed).

Tested by trying to commit invalid .liq file - failed as expected - thus merging.

@david Please note that liquidsoap-linting fails with current implementation and prints many deprecation warnings - should I create a ticket for that?

Does that mean you cannot commit because of deprecation warnings? Such warnings should usually be not a blocker for committing.

But in any case, yes please create a ticket to solve deprecation warnings. This ticket can also be linked to the Liquidsoap 2.2+ upgrade.

The reason I couldn't commit was an error related to a special liquidsoap installation used for testing another issue (#53). Assuming pre-commit hooks won't block since all tests in pipeline succeeded (same check).

Which Liquidsoap version are you using for #53? Please ensure it's the same as currently in main.

liquidsoap 2.2.0 - just posted current state and issues in #53.

@chrizz It should be liquidsoap 2.1.x though.
