fix: replace pre-commit with @fastify/pre-commit

The pre-commit package is unmaintained and carried a vulnerable version
of cross-spawn (CVE-2024-21538). @fastify/pre-commit is a maintained
drop-in replacement that ships with a safe cross-spawn@^7.0.3.

Also removes the now-unnecessary cross-spawn override.
