Allow figure dash and en dash as year separator in copyright

[fortysixandtwo]

These are valid characters to denote ranges.

I've came across this as an reproducibility issue here

[fortysixandtwo]

Mh, I don't quite understand why the unicode dash is not preserved in the generated html

it should hit this codepath:

    if copyright_line[5:9].isdigit() and copyright_line[9:10] in {'', ' ', ','}:
        return copyright_line[:5] + replace_year + copyright_line[9:]

but apparently it doesn't.

I'm having some issues running the testsuite, so any help/pointers would be appreciated.

Hi @fortysixandtwo! I attempted something similar recently (except without figure-dash support) in #12450 -- although discarded that after learning that some projects are intentonally using non-hyphen dashes for a workaround that it provides: it disables the copyright-year substitution on their copyright notices.

I don't think it'd be great to merge this if we know it's going to break their workflows -- but I do also agree in theory that it'd be nice to support other forms of year-range separator.

Most of the notes and ideas I've taken about this are in #12451 -- I'd warn that there's a lot of me rambling to myself as I worked through the details, and the conclusions that I did reach have not yet resulted in any merged pull requests. If you have any time to add commentary / suggestions I'd be grateful - it's good to know that someone else cares about and is reading into this.

I don't want to be obstructive, and other maintainers could overrule me, but I do think that this change (although well-intentioned) would cause problems for some folks.

Closing per @jayaddison's rationale.
