Fix/remove failing release-drafter.yml job

[jescalada]

Recently, the CI has been failing due to the Release Drafter workflow in the "Validate and Label PR" job not working as expected (presumably due to a permission issue). The "Validate and Label PR" has been failing for a long time, despite the check passing.

A recent bump to the release-drafter action has made it so that the job actually fails now, thus blocking our PRs.

Describe the solution you'd like
Figure out if the Release Drafter is needed or desirable, if so fix it, if not remove.

@finos/git-proxy-maintainers Fixed this in #1482 by adding write permissions to the release-drafter action. This successfully generated a v1.20.0 draft release. I'm guessing fixing this will help us automate most of our release process excepting major releases!
