#672 Add documentation to the dist.

[adiroiban]

Description

Fixes #672

Update the pyproject.toml

How to test

Run python -m build.
It will generate .tar.gz and .whl files inside the dist/ folder.
Check that the documentation source files are included in the .tar.gz version.
Check that the documentation files are not included in the .whl version.

.whl is just a zip file.

LGTM. I do notice that there are some files in the .tar.gz that probably should be omitted:

towncrier-24.8.0.dev0/.github/CODEOWNERS
towncrier-24.8.0.dev0/.github/PULL_REQUEST_TEMPLATE.md
towncrier-24.8.0.dev0/.github/workflows/ci.yml
towncrier-24.8.0.dev0/.git-blame-ignore-revs

Perhaps also these, as I can't imagine that pre-commit is run by packagers:

towncrier-24.8.0.dev0/.pre-commit-config.yaml
towncrier-24.8.0.dev0/.pre-commit-hooks.yaml

None of that blocking, though. Feel free to merge. Thanks!

Many thanks for the review.

I will exclude github and pre-commit files.

Perhaps also these, as I can't imagine that pre-commit is run by packagers:

I think that the idea of source dist, is not necesarily to be used by the packages, but to allow a person to do software development ... without git clone

I have also removed the pre-commit config.

The developemnt of towncrier should be done using git clone and pre-commit doesn't make much sense without git.
