add support for Gnome 47

[thekswenson]

The extension doesn't currently work with Gnome 47 (ubuntu 24.10).

I noticed that @DisDis has made changes for Gnome 46: DisDis#1
I will try to clone these changes and update the metadat.json files. With luck, this will be enough to run cpufreq in GS47.

I've cloned this repo: https://github.com/gilvbp/cpufreq/tree/gnome_46 (and switched to the gnome_46 branch)
After running autogen.sh I change the version numbers in metadata.json. Then I can enable the extension in GS47.

There is a problem, however, in that the cpufreqctl commands use 100% cpu for some reason. I have to disable the extension and then kill the many cpufreqctl commands spawned by the process.

The strange thing is that, if I call the command myself:

/usr/bin/pkexec /usr/bin/cpufreqctl --governor --core=3 --set performance

there are no issues, and the command terminates normally.

Yes, I am sure there are a lot of people who would love to have a version of this extension for Gnome 46/47, including me. I wish I could help...

The extension doesn't currently work with Gnome 48.
Seems to be dead...
