3.x documentation with the separated theme #116

Hello,

https://ruby-doc.org/ offers pointers to many docs, and for Ruby releases there are two categories:

• The "Complete" docs ;
• The separated docs : "Core" and "Standard Library".

The separated ones use the theme of ruby-doc.org, centred with – I find – a more legible theme. Compare:

1. https://ruby-doc.org/core-3.1.1/Enumerable.html
2. https://ruby-doc.org/3.1.4/Enumerable.html

Is there any chance to get the separated docs for the latest Ruby releases (the last "Core" + "Standard Library" is 3.1.1) in that format? Or hamornise the theme and always use the ruby-doc.org theme?

Thank you.
