Allow Sphinx v6

[lafrech]

Copied on https://github.com/Chilipp/autodocsumm/pull/79.

I'd only test against each supported Sphinx major version, but that's not my call.

Sphinx 6 dropped Python 3.7.

I reworked the test matrix. @Chilipp feel free to close this and define the test matrix you find appropriate.

Thanks @lafrech !
