ENH: Update CFF with publication reference, Zenodo DOI, and other details
Continuing in the spirit of #54241, this PR adds some further information to the CITATION.cff file, including a reference to [McKinney (2010)](https://doi.org/10.25080/Majora-92bf1922-00a), the DOI of the software itself ([10.5281/zenodo.3509134](https://doi.org/10.5281/zenodo.3509134)), a link to the [team page](https://pandas.pydata.org/about/team.html) on pandas' website, and a couple more keywords that bring this list into alignment with what the GitHub repository displays.
Thanks @cgobat
