`wget` might be more reliable for downloading things, which is performed in this module.
Some user faced the error with extension that didn't download fully, causing the `unzip` command to fail.
I tested the same extension & it installed successfully for me.
This was maybe a server error, maybe `curl`'s, but I will still do this change, as I have more trust in `wget` for strictly downloading things.
If you wished to install some Gnome extension, but couldn't find it in RPM, this extension will help you in that.
Basically all extensions are supported, with some rare extensions like Pano just additionally needing some system dependencies.
See README for more details.
