Why this should be merged

How this works

How these changes were tested

To prevent any errors while building

• run vale /docs/file/path on all changed .md files to ensure all grammar rules pass
• run markdownlint /docs/file/path on all changed .md files to ensure all linting rules pass
• complete the above two checks and all additional rules outlined in style-checker-notes.md to
  ensure all checks pass

If a document was removed/deleted

• the path to that doc must be redirected to a valid URL via the
  _redirects file
• _redirects were manually verified with the cloudflare preview link
• sidebars.json reflects all changes made to file path

If a document was moved

• all files that were moved from their current directory to a new path have had their paths
  redirected via the _redirects file
• _redirects were manually verified with the cloudflare preview link
• sidebars.json reflects all changes made to file path
