docs(tooltips): update ux guidelines

[panch1739]

This PR updates the tooltip docs based on the latest Element decisions.

@kfenner This should only be merged when we implement the tooltips coherently in our components. Im unsure if we plan to do it for V49...change it if is not the case (L)

LGTM 👍

@spike-rabbit @dauriamarco Please review as well 🙏

And, I think we should do this for v48 as it's requested by project(s). If something would require a breaking change, then we should do it for v49 but I don't think that'd be necessary.

Thanks @panch1739 for the update and for the research you did on the topic 🚀

Replying to @kfenner as well:
I’m currently updating my old tooltip PR #778, also as a follow-up to the discussion with Maxi here which should be directly related to this topic.

That PR will very likely be breaking, since the input triggers will be completely removed in order to make the tooltip compliant with the new guidelines.

I’ll keep you posted once the update is ready 👍

UPDATE: I've opened a new pull request to address the alignment: #1245
