Always use content to resolve content type in resources.GetRemote

This is a security hardening measure; don't trust the URL extension or any `Content-Type`/`Content-Disposition` header on its own, always look at the file content using Go's `http.DetectContentType`.

This commit also adds ttf and otf media type definitions to Hugo.

Fixes #9302
Fixes #9301
