CI tests failing with "Test_ArgoDocs::test_search[docid=None-where=abstract] - KeyError: 'AB'"

[gmaze]

Some CI tests, apparently quite randomly, fail with a:

FAILED argopy/tests/test_related.py::Test_ArgoDocs::test_search[docid=None-where=abstract] - KeyError: 'AB'

eg with:
https://github.com/euroargodev/argopy/actions/runs/10940750386/job/30373858695#step:11:1683

gives the error trace:

that is very weird because this test is supposedly using a mocked http server, hence correct and always available data !

Most of the time, re-launching the failed test will make it pass on the 2nd attempt
