Created a new label Z-Element-R-Rollout-Blocker if an issue is discovered

Edit: We can re-use the existing Z-Element-R-Blocker for that

[t3chguy]

@BillCarsonFr the canonical source for labels is a YAML file, otherwise it'll be deleted by the automation.

Ok I think we can just re-use the existing Z-Element-R-Blocker then? As it won't be used anymore

This is incorrect (unless we deliberately make it so). config.json changes are independent of releases.

I'm going to reopen this until the rollout actually happens (and we have migrated all users on app.element.io to rust)
