### What?
This PR fixes numerous links across the docs, both internal docs links
and external links. This PR also fixes some minor formatting issues in
some places, as well as optically aligns the markdown tables in tables
that had broken links.
### Why?
To properly link readers to the correct location in the docs, and for
better formatting and easier consumption.
### How?
Changes to many `.mdx` files in the `docs` folder.
Notes:
- There are duplicative section id's in `docs/authentication/email.mdx`,
I've fixed one such link, but have left it as is for now.
### What?
I noticed a spelling error in the banner of the beta docs and decided I
could save everyone some time by *running the entirety of the beta docs*
through a spellchecker.
### Why?
To fix many spelling and formatting mistakes at once.
### How?
By enabling `edit mode` in my browser and letting the built-in
spellchecker perform its magic (and changing _only_ where it made
sense).
~~Ironically, the original spelling mistake that inspired me to do this
remains unchanged as that is a part of the website repo. [PR for that is
here](https://github.com/payloadcms/website/pull/388).~~
