Add UltraFeedback

[alvarobartt]

Description

This PR adds the UltraFeedback task, but improving some parts from the former implementation within the main branch of distilabel, as that was not a faithful reproduction of the original paper of UltraFeedback.

So this PR adds a more faithful implementation such as fixing the system_prompt used, better output parsing/formatting, while still keeping the former text-quality task now renamed to quality-assessment task, not defined within the original paper, but kept there because computing individual scores can get way more expensive, and it's proven to work fine.

Closes #437

@alvarobartt please keep the overall quality task. It's there for a reason and it's the one that has been working best. The others mean that we need to run N judges to get the overall rating which is extremely costly.

As discussed, we don't have to provide faithful reproductions if we can improve existing approaches.

I would choose a better name than text quality, because it's really and overall assessment of the response.

Fair, consider it done! 👍🏻 Thanks for the feedback!

Also is overall-assessment fine for the name of that aspect?
