Teams review support

[volas]

Adds support for team review:

components:
  src/example.ts: org-name/team-name

But it does not work with standard github.token, for some reason github needs more permissions for team_reviewers ("Could not resolve to a node with the global id of ..." error or something). I have updated README with steps for generating and using own token for this.

@volas sorry to let this slip through the cracks. Is this something you're still interested in driving? I assume the / prefix is to disambiguate from usernames in text? What about org-name/team-name like github normally does? I know the org name will always be the same but I think reading it will be more obvious to most people.

@dyladan no problem, I was using this on my fork and dropped this here just in case if someone else interested.

I have updated it to use "org-name/" as team prefix.

And also updated Readme.md with instruction about using personal access token instead of github.token, because else action don't have permissions to request team review. This part can be little complicated.

If this PR gets merged this should point to the upstream repo or have a link independent of the repo name

Replaced it with a markdown table.

Also removed Discussions prem as it was unnecessary, I think.

Thank you @volas! We are looking for the same functionality, so glad to see you already worked on that.

FYI, I did a small test run for my PR towards opentelemetry.io, it seems to work:

https://github.com/svrnm/opentelemetry.io/actions/runs/9791445867/job/27035250030

There have been no reviewers assigned since it checked for open-telemetry/team-name which of course is not available in my privat repo.
