chore: Expand default hooks installed

When developers run `pre-commit install`, pre-commit by default only
installed the `pre-commit` hook. The configuration also makes use of
the `commit-msg` hook which would remain unused. The developer is
required to run `pre-commit install -t commit-msg` (in addition to the
default install), which they would only know from inspecting the
pre-commit configuration file.

By specifying both hooks in `default_install_hook_types`, a simple
`pre-commit install` will ensure that _both_ hooks are installed. This
should hopefully provide a better developer experience and catch a few
lints _before_ they are pushed to a branch and cause CI to fail.
