CI: skip notify-docs job when running in a fork

[0x53A]

see my comment here #933 (comment)

This workflow currently also gets triggered in a fork (if the fork has Actions enabled) because of:

  push:
    branches:
      - master

running the workflow in a fork doesn't hurt, since the fork can't actually update the docs, but not running it feels a little cleaner

API docs are being generated and will be shortly available at: https://godot-rust.github.io/docs/gdext/pr-945

Good idea! Can you check against the github.repository_owner instead? That doesn't break in case we rename the repo.

Also, this condition is currently on a job level -- does it not cause any issues if the workflow starts and its one job is skipped? Will it display as skipped or not at all?

(I don't think it's possible to have the condition on a workflow level, let me know if you find a way 🤔)

I have no idea, I'd assume it'll show as grey.

Yeah I couldn't find any if at the top level either

Thank you! 🙂
