Doc: Update FDW documentation about GetForeignUpperPaths().
In commit d50d172e51, which added support for LIMIT/OFFSET pushdown in
postgres_fdw, a new struct was introduced as the extra parameter of
GetForeignUpperPaths() set for UPPERREL_FINAL, but I forgot to update
the documentation to mention that.
