Legacy Template Block: Remove the deletion lock (https://github.com/woocommerce/woocommerce-blocks/pull/5166) (https://github.com/woocommerce/woocommerce-blocks/pull/5176)

Previously, our legacy template block was locked to prevent the users from
removing it. The block could however be removed by erasing the parent, so
this change allows the user to directly remove the block itself.
