Feat/traveling ruby 3.2.2

[YOU54F]

Hey hey, I've been working on traveling-ruby as part of this PR

I made some updates to this project, to utilise the latest release from the traveling-ruby fork in order to build for the latest ruby version (but also exposes multiple ruby versions 2.6.10 -> 3.3.0-preview1)

Noted some of the things that were on my work list, when reviewing the project and working through it.

• remove traveling-ruby source from repo
• provide download task to be run to provide updated runtime
• provide mechanism to use other ruby versions other than 3.2.2
• download only specified target if it doesnt exist
  • YOU54F@3410a41
• update readme to state new platforms
• auto detect platform if not provided
• should we retain existing flags for target or add an arch flag
  • currently changed from l64 to lx64 (for intel) la64 for arm
  • ARM64 versions of linux and macos now provided (along with x86_64)
  • x86_64 versions of windows now provided (along with x86)
• Provide flag to use -full traveling-ruby runtime with all native gems
• Provide mechanism to fetch any required native gems from traveling-ruby source
• add fix for xattr warning when untaring file
• check exit code properly returned from script
• convert scripts to be sh compliant to remove bash dep
• test on windows
  • Note: no native gems on windows, supported via traveling-ruby

Also been working on another branch, which pulls in a traveling-ruby source, which has a load of Pact ruby gems included (an open source project), it tests out a load of native gems.

You may not want to use these but they can serve as reference to others and have been a useful example project in the wild for me to work with. Cheers!
