Add Github Actions automations (#4405)

* Add Github Actions automations

- labeler: used for versions and marking commits as Infra
- backport: we can now apply labels `backport $branch` and on PR close
this will automatically open up the appropiate backport PR's

If you call the release target e.g

$ ./build.sh release 8.0.0-alpha2

This will now bump the version in both global.json as well as the
autolabel.json

* fix casing on label

(cherry picked from commit f0ee705)
