Stop managing mime support package on Debian

[jcharaoui]

Summary

All apache2 packages on Debian 10 and later already have a hard dependency on the mime-support package. While mime-support still exists on Debian 12 as a transitonal package, upcoming Debian 13 has removed it entirely.

This sets the $mime_support_package to undefined so that the package isn't managed on Debian, since it doesn't need to be.

Additional Context

Currently, the module fails completely on Debian testing (upcoming release 13 codenamed trixie):

• 🟢 Spec tests.

IMHO the default should stay unchanged for Debian 11 and 12 for the time being. So maybe add something like this in params.pp:

if ($facts['os']['name'] == 'Debian' and versioncmp($facts['os']['release']['major'], '13') < 0) {...

Why, if the packaging already has a hard dependency then why not rely on that?

Accepting this change will allow Debian 12 users to get rid of the transitional, dummy package mime-support on their systems.

Sorry, misunderstanding no my side please ignore my comment

I approved CI, so waiting on that to finish.

Looks sane!
