Ruby_install

I removed everything ruby that came from repo, gem, rbenv.
Then installed 3.3.3 with ruby-build and set PATH in .bashrc.

All gems gone.. so I did:

• gem install httparty
• gem install nokogiri

..and will continue to add missing gems as I encounter them.

ruby -v ruby 3.3.3 (2024-06-12 revision f1c7b6f435) [x86_64-linux]
