Make some more improvements to parallel query documentation.
Many places that mentioned only Gather should also mention Gather
Merge, or should be phrased in a more neutral way. Be more clear
about the fact that max_parallel_workers_per_gather affects the number
of workers the planner may want to use. Fix a typo. Explain how
Gather Merge works. Adjust wording around parallel scans to be a bit
more clear. Adjust wording around parallel-restricted operations for
the fact that uncorrelated subplans are no longer restricted.
Patch by me, reviewed by Erik Rijkers
