Mention Dinnerbone as author

[PerchunPak]

I'd like to still give attribution to dinnerbone here. I'll look for a way to add py-mine to the list in pyproject.toml and use pkg_meta["authors"] here.

While Dinnerbone did author this project, I don't know if it's really fair to say that the copyright belongs to him, considering that at this point, not much of the code-base is actually his code anymore. I did some searching and found that from a total of ~3.9k lines of code, only 481 lines are still owned by Dinnerbone, which is just 12%. This number will also likely greatly decrease after some of the bigger PRs that are currently pending get merged.

I think that while Dinnerbone should be left in the author field, the copyright field can just stay as py-mine, giving credit to the whole development team of the project.

Copyrights can mention multiple people. Almost like a small history. Copyright protections last for 70 years.
