[FEATURE] Fall back to polling triggers if user is not a Linear admin #14904
Description
In #14876 (comment), we are throwing a blocking error for the webhook configuration if the user does not have an admin role in Linear.
Instead of throwing a blocking error, we should instead fall back to a polling trigger, and have an info alert prop that highlights this behavior - that if you are an admin, the trigger will be set up as webhook, but if you are not, this should default to polling.
