When I want to go to a game forum on GOG Galaxy to ask a question about a game I'm playing, I currently seem to need to navigate to the GOG store, find the game there, go to that game's GOG store page, and then click the forums button there to get to the GOG discussion forums for that game.

It would be sensible for GOG to allow me to right click the game in my library, and put an option in the right click menu there to go to the forums for the game so I can bypass the store searches to get to that game's GOG forum.

Context menus are a tricky beast. What you speak of would technically be possible, but given that Galaxy is nothing but a thinly framed gated browser in that aspect, and as such takes to the same limitations; and is in fact worse than the userscripts the users around her use, like Barefoot Essentials 2 or Adalia Fundimentals.
