So I completely closed Galaxy and deleted
steam_[..a bunch of numbers..]-storage.db file from %programdata%\GOG.com\Galaxy\storage\plugins\
and
steam_[..a bunch of numbers..] folder from %localappdata%\GOG.com\Galaxy\plugins\installed\
After the next Galaxy launch, I was able to download the new Steam plugin in the integration settings.
Connected again, and everything is working fine so far.
YOU NEED TO DELETE BOTH OF THOSE. Deleting the plugin only from appdata doesn't fix it.
