External tool API tests failing on Rocky 9

[pdurbin]

A little bird told me API tests are failing on Rocky 9. We diagnose and fix them. I'll give this issue a 10 for now to investigate and fix what we can.

Meanwhile @donsizemore already has a Rocky 9 branch going as part of this issue:

• Rocky 9 is out gdcc/dataverse-ansible#243

Just this morning I suggested it to someone who was having trouble installing Dataverse.

There's also an existing issue about updating our guides for RHEL/Rocky 9:

• documentation update: RHEL 9 #8856

This new issue I'm creating now is focused on the API tests.

current failing test in develop on Rocky 9 (though failures are inconsistent):
[ERROR] ExternalToolsIT.testDatasetLevelTool1:211 1 expectation failed.", "JSON path data[0].displayName doesn't match.", "Expected: DatasetTool1", " Actual: Whole Tale"

I put in a fix for one of these tests on a branch revising the ExternalToolsIT. I can take care of this one and any others
