Merge pull request opendatahub-io#938 from red-hat-data-services/revert-935-update-sa-merge

Revert "RHOAIENG-26264: switch `GITHUB_TOKEN` to `GH_ACCESS_TOKEN` in `instant-merge.yaml` and remove unused permissions"

* Reverts red-hat-data-services#935

This thing did work, as documented on https://issues.redhat.com/browse/RHOAIENG-26264, but there are some trouble with accounts and permissions remaining, that I am unable to resolve on my own or with the help of other IDE team members. Therefore, I strongly believe it's best to back off for now and try again later.
