Style and link fixes

[alexandratran]

Description

Make various fixes and enhancements:

• Remove category pages that only have an autogenerated index file. These pages add bulk and redundancy to the site. Add link fixes and redirects as needed.
  • Fix styling so all collapsible category links have the same dropdown arrow, whether or not they have an index page.
• Fix styling for tables and OpenRPC reference: add proper styles for links and code formatted text.
• Fix indentation for nested ordered lists.
• Add more items to "What's new?" for June.
• Remove Keyring API doc tags (these are not necessary, as these pages have "see also" links).
• Remove announcement bar.
• Remove some unused files.
• Other minor link fixes.
