The user can opt to not delete the webhook (if installed) when removing
the entity from garm. Garm will only ever try to remove a webhook that
exactly matches the URL that is composed of the base webhook URL configured
in the config.toml file and the unique controller ID that is generated
when the controller is first installed. It should be safe to remove the
webhook when the entity is removed.
Of course, this behavior can be disabled.
