Add OperaGX to the list of permitted browsers

[demonitized]

OperaGX should be marked as allowed, as it's still using Opera at it's core, and the User Agent still reports Opera, but for some reason it isn't being marked as valid.

Can you provide some extra information on what you're seeing @demonitized?

It looks like the User agent is:

Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/128.0.0.0 Safari/537.36 OPR/114.0.0.0

and looking at the Browse-happy api, it's returning old Opera data, but doesn't seem to be flagging it as insecure or outdated:
