Allow one GitHub organisation to be linked to more than one Sentry Organisation

### Problem Statement

As an agency with multiple clients, we usually hook them up with Sentry. Some of them are using their own Sentry plans, some are within ours. The problem is, that we cannot connect our GitHub orga to more than one Sentry orga. There's a couple of workarounds (like putting the affected repos into their own orga), but all of them are not really nice. It would be cool if things would just work out of the box.

Thanks for reading, hope there will be a way (not sure about technical limitations from GitHub's side)
