The url for downloading addons on Windows points to https://wingrass.fsv.cvut.cz/grass82/x86_64/addons/ when it should instead point to https://wingrass.fsv.cvut.cz/grass82/addons/.

For example https://wingrass.fsv.cvut.cz/grass82/x86_64/addons/grass-8.2.0/r.skyview.zip should be https://wingrass.fsv.cvut.cz/grass82/addons/grass-8.2.0/r.skyview.zip or perhaps https://wingrass.fsv.cvut.cz/grass82/addons/grass-8.2.0RC1/r.skyview.zip.
