Ability to change extension language

[RandomGuy28]

Is your feature request related to a problem? Please describe.

I think it's great that the browser extension is getting translated, but for someone like me who have different browser and Steam Store languages, it's a bit annoying to see two languages in the store.

Describe the solution you'd like

Add an option to change the browser extension language in Settings.

Describe alternatives you've considered

Read the language set in the Steam Store and set the browser extension language accordingly.
