[develop] Additional proofread of the docs (#209)

## Description
- Made sure the titles are identical between the index and each of the
page's headers.
- Removed "Joypad" as it's not a proper word used on N64's public-facing
reference documents.
- Added some of the writing included on the main branch.
- Added code tags to some button names I missed out.
- Other uppercasing fixes and nitpicks.

## Motivation and Context
Typo fixing, leaving the docs polished to the Nth degree.
