Sdist isn't getting published

[wallentx]

In our workflow, we are using pep517.build (which is deprecated) to build the wheel:

clvm/.github/workflows/publish-to-test-pypi.yml

Lines 32 to 44 in 26bb83c

	- name: Install pep517
	run: >-
	python -m
	pip install
	pep517
	--user
	- name: Build a binary wheel and a source tarball
	run: >-
	python -m
	pep517.build
	--binary
	--out-dir dist/
	.

We aren't building the sdist.
If we were to use pip install build, and then
python -m build --outdir dist/ ., this should provide the sdist and the wheel to publish to pypi.
