[PATCH worg] ob-doc-python: Use ":results file link" for returning filenames

[~jackkamm <jackkamm@git.sr.ht>]

From: Jack Kamm <jackkamm@gmail.com>

The correct usage for returng filenames as paths is to use the link
header arg.  This updates the ob-doc-python examples to follow this
convention now.  See also:
