[BUG] Package data missing with Setuptools 61

I’ve been fighting building one of my projects this evening, finding that all of the package data is missing.

$ pip-run -q recapturedocs==5.0.1 -- -c "import recapturedocs, os; assert 'prod.conf' in os.listdir(os.path.dirname(recapturedocs.__file__))"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
AssertionError

But if I instead build with setuptools<61 (by changing the pyproject.toml), the content is present.

$ git -C ~/m/recapturedocs diff
diff --git a/pyproject.toml b/pyproject.toml
index 190b355..cfacc1a 100644

I haven’t yet had a chance to investigate why, but I wanted to register this issue.
