Summary:
PG commit cc50080a828dd4791b43539f5a0f976e535d147c added VACUUM ANALYZE on tenk2. YB commit 9645d0c1c3b0da0defe2e7ce4f02d7abd819bfa1 (D37015) incorrectly removed it. Add it back.

VACUUM ANALYZE changes the plan of a query in yb_select_parallel. Update the expected output accordingly.

Test Plan: Jenkins: rebase: pg15, test regex: TestPgRegressParallel*
