Current version in master breaks CI

Hi @PurplePachyderm, the latest merge in master (PR #214) breaks the CI. Is this something we can fix?

Thanks !

Hi @pablooliveira

I just started looking into it, so here's what I can say for now :

• I had noticed in the past that the CI would rarely but randomly fail on one of the tests (this one, if I remember correctly). I never figured out why this happened and never experienced this issue anywhere else, but re-running the CI manually would often make it pass.
• I just tried to re-run it manually to see if this was this issue or something else, but it seems the Ruby packages that we use have changed, and the CI now fails even earlier during the install :

sudo gem install ronn-ng
ERROR:  Error installing ronn-ng:
	The last version of nokogiri (~> 1, >= 1.14.3) to support your Ruby & RubyGems was 1.15.6. Try installing it with `gem install nokogiri -v 1.15.6` and then running the current command again
	nokogiri requires Ruby version >= 3.0, < 3.4.dev. The current ruby version is 2.7.0.0.
Error: Process completed with exit code 1.

I will recreate a Docker container based on our image to fix this and investigate the issue (maybe we can even get rid of the Ruby dependency ? I think we only use it to generate documentation, there is probably a Python package that would work for that ?).

I will keep you updated in the coming days!
