chore: issue forms with reason-listings

[CommanderStorm]

Does your PR solve an issue?

As discussed in https://github.com/launchbadge/sqlx/issues/3471, I have added a field to the form. I have also migrated to using issue-forms as they are a bit better too fill out and users are less likely to flat-out ignore the form.

You can preview it here:

Being upfront: It might take me a few days to address that changes (even though they are extremely minor), depending when I have the time to break out my laptop between sightseeing (GitHub mobile does not have an apply suggestion button, am currently on vacation ^^)

Sorry, hope that does not bother you too much

I neglected this for a bit, sorry. I think this is an improvement over the existing forms, we can iterate as things come up.
