Fix/release workflow (#5802)

Here is a fix for https://github.com/twentyhq/twenty/issues/5163

I tested it on another repo and should work as intended this time
arround.

I've created two workflows
- One that creates a PR
- The second that watch PR merge with specific labels
- I also check the author of the PR to make sure it was created by a bot

You can now disable the creation of the a draft release
