This fixes a build error by including the requrements-docs.txt file as a data file

[peytondmurray]

Hmm, I was able to build locally with pip wheel . and with python -m build ., so I can't seem to replicate the error here. pip wheel doesn't build in isolation, though, so I guess it still has access to the requirements file. And I guess python -m build . must copy the entire source tree to a temporary directory (because it does build in isolation, in /tmp). But I'm okay including this as a data file.

python -m build . reproduces the build failure locally for me:

Whoops, yep my branch was out of date 🤦

Confirmed this PR resolves the issue. Thanks!
