Possible speedups (#15)

* Update to Fedora 41 with dnf5

This should be faster, see
https://fedoraproject.org/wiki/Changes/ReplaceDnfWithDnf5

> Significantly faster for many user cases
> Optimization of download metadata

Fedora 41 is currently still in beta, but if this causes trouble, we can always revert.

Related to #8

* Disable extra repository with a multimedia codec

The repository is enabled by default but we don't need it.
By explicitly disabling it, we prevent unnecessary metadata fetch.
