@ronaldtse in original Travis configuration, we tested different rnp versions only against ruby 2.5. some questions regarding this:

• do we still need it?
• should we test it on other ruby versions too?
• do we need to test on macos and windows too?

[ribose-jeffreylau]

@CAMOBAP I think we can test against Ruby 2.6, 2.7 and possibly 3.0, since 2.5.9 is EOL'd.

As for macos and Windows, they're nice-to-have targets but not a high priority, since tests on those platforms in https://github.com/rnpgp/ruby-rnp should ideally give us enough confidence that they'd also work when Linux works.

@ronaldtse the workflow by itself work, after several fixes I ended up with
