PG17 compatibility: ensure get_progress() output is consistent (#7793) 

in regress test isolation_progress_monitoring, with an ORDER BY. The
implementation of get_progress() uses a tuplestore to hold the step and
progress values, and tuplestore does not provide any guarantee on the
ordering of the tuples so ORDER BY ensures stable test output. Also make
the output more user friendly by including the column names. Fixing
occasional failures seen in isolation_progress_monitoring.
