On PG15 new flag CUSTOMPATH_SUPPORT_PROJECTION is introduced. This flag tells if a planner node is projection capable or not. CustomScan created in TimescaleDB by default is not projection capable, this causes CustomScan node to be wrapped around Result node. Update query on a hypertable has a logic which is based on assumption that "ModifyTable" plan nodes lefttree should be CustomScan node. With PG15 this assumption is broken which causes "ERROR: variable not found in subplan target list". Fixes #4834
