Update config.yml to add Donate page to the nav bar
It would also be really great to enable GitHub sponsors specifically for the Pandas Org since people might want to sponsor the org directly on GitHub (dev's / org's want to highlight their sponsorship publicly so GitHub sponsors is a great way to do so).

Yeah that is a fair point! Just wanted to suggest this, let me know if I can be of any help on GitHub sponsors. I created #47960 to open a discussion with your points, probably better than using this PR. I see that we're using this for GitHub sposnors: https://github.com/pandas-dev/.github/blob/4af72faf8bd1e0f1d3f12401c559a3a4b2a9a68b/FUNDING.yml

If you want to add a quick description on what it'd take what you suggest, that'd be amazing. I don't really know much about it. Closing this in favor of the discussion that was opened!
