[PATCH] doc: outline all planner nodes

Hi,

The docs doesn't currently list all the planner nodes. I wrote a patch to add a new section "14.3" that outlines the different types.

I took the compiled HTML page and hosted it on Netlify to make it easier to peruse:
- https://lovely-lebkuchen-c79301.netlify.app/

Apologies if this isn't formatted normally. This is my first time contributing to the PG project directly.

Best,
Brian B.

I didn't see this registered in the commitfest app, if it is there I simply
failed to search for it. If not, please register it there to keep it top of
mind when work on finalizing v19 slows down.

Added a full list of the nodes with examples
to Section 14.3. Instead of explicitly outlining all parallel nodes, a reference was instead added to "15.3. Parallel Plans".

The original patch was updated to:
- improve language
- add an example for CTE Scans
- fix inaccuracy around Index-Only Scans
- remove typos

Sorry about the confusion. Added the patch to commitfest.
