Fix OBS link and fedora 37 support

[LeSnake04]

Is your feature request related to a problem? Please describe.
The current repo link in the readme is invalid and all packages on OBS are only for fedora 36

Describe the solution you'd like
Please link a official build for fedora 37

Additional context
This program looks like a good replacement for the gnome extension "cpu power manager" which doesnt have gnome 43 support yet, so an up to date official fedora repo would be great.

I just logged-in to OBS and the cpupower-gui repository was removed 5 days ago. It doesn't say why it was removed though.

I will have to make a new repo I guess.

Hi!
Noticed that package couldn't be updated by DNF anymore, since a week or so.
Please, rebuild the repository.

Many thanks for the good work! 👍

I still get errors with Fedora 37, any updates on this ?

[LeSnake04]

I found a working package for fedora 36 and 37: https://copr.fedorainfracloud.org/coprs/phantomx/chinforpms/package/cpupower-gui/

Thugh i dont recommend the repo and just download the rpm instead.

I have updated the OBS link in README. You can install cpupower-gui from the this repo https://software.opensuse.org//download.html?project=multimedia%3Aproaudio&package=cpupower-gui

It has the latest version from master, not the latest release (which is a bit dated).
