3.2.3: pytest is failing in `::project` unit

[kloczek]

I'm packaging your module as an rpm package so I'm using the typical PEP517 based build, install and test cycle used on building packages from non-root account.

• python3 -sBm build -w --no-isolation
• because I'm calling build with --no-isolation I'm using during all processes only locally installed modules
• install .whl file in </install/prefix> using 'installer` module
• run pytest with $PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>
• build is performed in env which is cut off from access to the public network (pytest is executed with -m "not network")

Here is pytest output:

::project is what pytest-checkdocs generates. I'm transferring the issue there.

[jaraco]

Similar to jaraco.packaging, pytest-checkdocs uses build.util.project_wheel_metadata to load metadata for the wheel. https://github.com/pypa/build/issues/556 tracks the limitation that it's not possible to load wheel metadata without building an environment requiring network access. Now it's clear why https://github.com/jaraco/jaraco.packaging/pull/11 was a bad idea. It fixed the issue at the wrong level of abstraction, leaving pytest-checkdocs broken while fixing only jaraco.packaging.

This issue isn't going to be solved here - it needs to be solved in build.
