CI: Add ruby 3.0 build matrix, and remove 2.4

[aka47]

Ruby 3.0 got released some time ago, lets make sure it works in all cases with vcr

@olleolleolle any ideas on those 2 failing cucumber specs. I am missing a hint right now how this connects.

They are..

• bundle exec cucumber features/http_libraries/net_http.feature:143
• features/test_frameworks/test_unit.feature:6

* features/test_frameworks/test_unit.feature:6

Do they fail in isolation, locally?

Yes - they also fail locally on my mac. Not for ruby 2.7 - but with ruby 3..

@aka47 Then it looks a bit like the Webrick server never starts correctly

How about removing ruby 2.4 support for new releases? Nobody should use it anyways.. this is the warning I get when I install it..

WARNING: ruby-2.4.10 is past its end of life and is now unsupported.
It no longer receives bug fixes or critical security updates.

Removing 2.4 support would be good. #903

[olleolleolle]

Nice! We have gotten to green. I retitled, and added a small README change for precision.

[aka47]

Great. Lets squash and merge it then... :)

I would suggest to upgrade cucumber to 7.0 and remove the outdated typhoeus 0.4.0 patch and testing - ( it is from June 08, 2012) ) - does that make sense?

[olleolleolle]

@aka47 I agree with both efforts as separate Issues we would like to address!
