Allow leaving organization #414
Description
Users can now be added to an organization #401, but we have no option to leave.
This issue is about supporting leaving an org, it could be done in the CLI by running something like chainloop org leave --id [UUID of the org]
Note that we might need to control the case where this user is the only member of an ORG. We might not want to leave orgs stranding and instead suggest them to delete their account chainloop auth delete-account
