Release notes here in case anyone wants a quick look:

Ruby 3.0

Fedora 34 provides Ruby 3.0, the latest version of the https://www.ruby-lang.org/[Ruby language].

Notable features of Ruby 3.0, compared to previous versions:

• The ability to run concurrently is updated with regards to Ruby 2.7, with Fiber Scheduler and the preliminary addition of Ractor.

• Static typing: RBS provides a foundation for allowing programs written in Ruby to define types. Ruby remains a dynamically typed language by default, but RBS acts as an additional (foundation) layer of a program to provide static type functionality and gain some of the benefits of a statically typed language.

• IRB gains some performance advantages: it is quicker, and now one can measure the execution time using the measure command.

• Standard libraries are updated.

• Pattern matching is now a stable feature.

See the https://www.ruby-lang.org/en/news/2020/12/25/ruby-3-0-0-released/[release notes] for more information.

Looks good to me, if anyone has any updates they can open another PR later. Thanks!
