Address flaky tests of `.adb` on Windows GHA runners

[khaeru]

For the "pytest" GitHub Actions runners, jobs running on Windows are fail sporadically with:

_______________________ ERROR at setup of test_convert0 _______________________

…for instance here.

These appear as ERROR or FAIL depending on which test first runs into the issue. They may have to do with incomplete responses from the ATO server.

To resolve:

• Identify the cause.
• Apply mitigation or fix. For instance, one or more of:
  • Mark as XFAIL.
  • Use pytest-rerunfailures.
  • Cache the files/responses.
