Diversity, Equity, and Inclusion Statement

I'm going through the CZI EOSS application process now. They ask for any information that our project has on our efforts to promote diversity, equity, and inclusion within our contributors and audience.

_Advancing DEI is a core value for CZI, and we are requesting information on your efforts in this area. Describe any efforts the software project(s) named in this proposal have undertaken to increase diversity, equity, and inclusion with respect to their contributors and audience. Please see [examples](https://apply.chanzuckerberg.com/protected/resource/eyJoZnJlIjogOTQ1ODEyNDksICJ2cSI6IDEyNDA2Mn0/) from successful first cycle applications ​(maximum of 250 words)_

Other than generally trying to be good and welcoming human beings I don't think that we've done anything explicit here. Should we? Are there things that Dask community members are willing to take on to improve the situation? This might be things like mentoring interns from Outreachy?

It's symbolic, but we might also consider adopting a statement like the following: (lifted from PSF)

_The Python Software Foundation and the global Python community welcome and
encourage participation by everyone. Our community is based on mutual respect,
tolerance, and encouragement, and we are working to help each other live up to these
principles. We want our community to be more diverse: whoever you are, and whatever
your background, we welcome you._
