Add regression tests for pg_stat_progress_copy.tuples_skipped.

Browse Source 
This commit adds tests to verify that tuples_skipped in pg_stat_progress_copy
works as expected. While existing tests checked other fields, tuples_skipped
was previously untested.

This improves test coverage and ensures accurate tracking of skipped tuples.
