CI: Apply UTF8-CLI patch to ruby/spec

```
1)
URI#select conforms to the MatzRuby tests FAILED

D:/a/rubyinstaller2/rubyinstaller2/ruby/spec/ruby/library/uri/set_component_spec.rb:9:in `block (2 levels) in <top (required)>'
D:/a/rubyinstaller2/rubyinstaller2/ruby/spec/ruby/library/uri/set_component_spec.rb:5:in `<top (required)>'
```
