I tried bisecting and got to this commit
11a896652ee98aa44e59ed25237f9efb56635dcf (issue33375) . Seems this changes
warning reporting output to add filename. I guess it's better to change the
doctest to adopt this change. I have added the devs on the issue for
confirmation.
commit 11a896652ee98aa44e59ed25237f9efb56635dcf (HEAD)

bpo-33375: Get filename for warnings from frame.f_code.co_filename (GH-6622)
More consistent with how other parts of Python find the filename (e.g.
tracebacks and pdb).
$ cat ../backups/bpo36695_1.py
def foo():
'''
>>> import warnings, io
>>> from contextlib import redirect_stderr
>>> f = io.StringIO()
>>> with redirect_stderr(f):
... warnings.warn("'foo' has no 'bar'")
... err_cap = f.getvalue()
>>> print(err_cap)
'''
pass
