Avoid delaying automation/script startup for sample blueprints (#114277)

Avoid delaying automation/script startup to check if the blueprint folder exists

automations and script both populate sample blueprints if none exist

The check to see if the blueprint folder exists always had to create
an executor job which would delay startup a bit if the executor was
busy. Since we do not need the sample blueprints to be populated
until the start event, we can run this in a task.
