meta: Define and list "Authors" and "Maintainers" for PyPI metadata

[dgw]

I'll let you open the issue for the list of authors/maintainers.

As above, we would like to fill out the list of authors/maintainers in project metadata in the wake of #2328. That means determining 1) who should be listed in each category and 2) filling in those lists. Optionally, 3) add more categories (e.g. differentiate between "authors" and "contributors"), but I'm not able to tell if that is supported by PyPI/packaging tools.

"Maintainers" especially are meant to offer a point of contact, the people to reach out to with problems or suggestions, because they're the ones working on the code now. The "Authors" field is less clearly defined, because if the original authors aren't involved any more and/or little-to-none of the original code remains, the utility to the users of seeing that information is minimal.

My rough list of "Authors" would include (from memory) sbp, myano, Embolalia, and anyone else who made major contributions to previous "generation" of the software (phenny -> jenni -> willie -> sopel). "Maintainers" would be some active subset of the "rockstars" group. Beyond myself (dgw) and Exirel, that idea gets vague very quickly. It might be best to decide partially based on who wants to be listed—that is, who's willing to be the project's "public face" in case anyone actually uses the contact info bundled with the package. 😁

Speaking of the @sopel-irc/rockstars, any of y'all have different opinions?
