Revise diversity and mental health sections for clarity

What changed:

• BIPOC is too far out of the European context, so more European context marginal groups are added
• "Sometimes we feel guilty" feels a bit patronising, so change from "guilty" to "difficulties"

I like it - thanks!

I think guilty could be appropriate too, but I'm fine with difficulties as well.

Thanks, that makes sense.

• We had some discussion about this wording, and some people felt that starting with “we feel guilty” might frame the experience a bit too strongly. We did not really come up with a perfect replacement, so I am also not sure whether it is necessary to change it.

• Also, last year we discussed some broader points about the lab philosophy; see Notes of Lab Philosophy in the Wiki. However, we did not manage to organize a follow-up meeting to discuss them further. For example, we talked about the Ombudsperson / trusted contact, and about the lab mission: how to bring the lab together as a whole and improve collaboration. It would be great if we could also integrate what we discussed during this year’s retreat.

We discussed it in the group meeting and these are excellent changes :) merging now
