chore: Use `committed` instead of `conventional-pre-commit`

The most important difference in this PR is that we now enforce scope
and subject line length. `conventional-pre-commit`, which we have been
using until now, does not appear to allow that unlike `committed` which
we will be now using.

On the other hand, `committed` doesn't allow to require having a scope,
unlike `conventional-pre-commit`, but I will probably submit them a PR
for this later.

I also find it questionable that disabling particular checks is to be
done by switching boolean options to false. Doing so by string options
would be more future-proof.

Also note that this has a check to make sure the commit message starts
with a verb. I am fine with this myself, but it may be an overkill.
