Build only one universal wheel when running tox

[hynek]

Sadly, hatch-autorun and tox seem to be fighting over env variables so we create the pth file by hand.

OK, this is interesting. @gaborbernat it looks like SETUPTOOLS_SCM_PRETEND_VERSION is not passed through when using the shared build environment despite being in [testenv]'s pass_env.

I couldn't find a way to affect env variables for it (which is why I gave up on hatch-autorun that needs one) – any advice? Would you consider this a bug in tox?

You're welcome!

Note the new config subcommand tox c -e py311 -k pass_env set_env that would have allowed you to inspect these settings.
