Closes: #21895

Have been using this template for close to 2 years (something broke then - symlinks/svgs metadata/both/something like that), after that never looked at upstream again - turns out development of the icons set got frozen and the upstream github repo is archived. 

I know Void usually doesn't include non tagged releases, but I think this falls under the exceptions.

For the record, if I recall just around 100-150 files got broken (so not a lot of icons, as they are included in several sizes) and probably not a lot of people use it, that can explain why there weren't more complains.

A patch file from https://github.com/void-linux/void-packages/pull/36861.patch is attached
