The Grand Reformat (#3643)

* The Grand Reformat

- everything made prettier...literally
- some tweaks to include a few more files, including documentation
- minor changes to format style
- some tiny `// prettier-ignore` changes to keep a few things the way we like them
- a couple of super minor tweaks to embedded document types to ensure they format correctly
