Build Ruby Gem: Some jobs were not successful

[aerimforest]

Hi, first of all, thank you for your wonderful theme.
If I modify the file and push, three workflows will be executed as shown below, and the Ruby Gem build will eventually fail like in the picture.



When I click on the failed workflow, it says test (2.6) failed.

If you look at the log, there is an error. I really don't know how to fix the error.

ERROR:  Error installing type-on-strap:
	The last version of rouge (>= 3.0, < 5.0) to support your Ruby & RubyGems was 3.30.0. Try installing it with `gem install rouge -v 3.30.0` and then running the current command again
	rouge requires Ruby version >= 2.7. The current ruby version is 2.6.10.210.  

I tried gem install rouge -v 3.30.0 and updated ruby. but it's still the same.

Ah it seems Rouge is dropping support for Ruby 2.6, I don't see it in their GitHub action anymore: https://github.com/rouge-ruby/rouge

In my case I think it's Rouge 3.26.0 that is installed.

Let's remove 2.6 and add 3.1 instead.

@sylhare Wow the error is resolved.
Thank you so much:-)
