Stack Overflow plugin support for PAT authentication

[cmdkeen]

Hey, I just made a Pull Request!

Fixes #15770 by adding support for the new PAT authentication for Stack Overflow as per docs.

Deliberately keeping as a minor change - I've not bumped the default API version number and added a new optional parameter. This is because it isn't clear whether the API key approach is still required for other Stack Overflow integrations.

My first PR against Backstage - great documentation but apologies in advance if I've missed anything!
