DOC: automatic 'end' year of copyright

#31022 Updated it after nearly 6 years, I think this will update with each new merge, so that should not be a problem from now on, (I think)

Makes sense, looks good to me.

In general I think it's better to import datetime, since when reading code datetime is ambiguous, but datetime.datetime is not. But not a big deal, we have imports like this everywhere in the code, just saying.

Do you mind if I open a pull request addressing these?

Better open an issue first, so there is some discussion and you see if there is agreement in it.
