PR summary

This PR fixes three outdated information in doc/install/:

  • (i) Removes ttconv from the bundled library list. It was removed in Matplotlib 3.10.
  • (ii) Updates the environment variable and troubleshooting pages with the Windows config and cache paths. Since 3.11, both default to %LOCALAPPDATA%\matplotlib. If %USERPROFILE%\.matplotlib already exists, that directory is used instead. Updates the Windows examples to match.
  • (iii) Clarifies that Linux and FreeBSD use separate .config and .cache directories by default, while macOS uses ~/.matplotlib for both.

AI Disclosure

Claude Code (Claude Sonnet 5.5 (high) ) found these during docs audit.

Looks like that suggested change removed .. envvar : : MPL_IGNORE_SYSTEM_FONTS even though that doesn't show anything removed,
