Greasy Fork is available in English.
Adds links for GOG store to gameplay videos without youtubers comments and direct search on Gog-games for free clean download.

Give it a couple of minutes and update so it applies your suggested fix.
For some reason, even after using the same "namespace" the script refuses to be seen as an update and rather works as a new script, so you will have to reinstall it instead of just updating. Sorry for the inconvenience.
Two changes to make it work with any language:
// @match https://www.gog.com/en/game/*
to
// @match https://www.gog.com/*/game/*
url: "https://www.gog.com/en/game/*",
to
url: `https://www.gog.com${location.pathname.replace(/\/game\/.*$/, "/game/*")}`,
