ci: tests for driver manager on windows don't seem to be executed

### What happened?

It looks like tests for the driver manager are not executed on Windows during CI runs.

- Workflow: Native Libraries (Windows)
- Job: C/C++ (Conda/windows-latest)
- Step: Test Driver Manager

Here are a few concrete recent examples:
- https://github.com/apache/arrow-adbc/actions/runs/9111616483/job/25049100520#step:10:1
- https://github.com/apache/arrow-adbc/actions/runs/9103078697/job/25024128623#step:10:1
- https://github.com/apache/arrow-adbc/actions/runs/9099930912/job/25013632462#step:10:1

In the output of all these step we don't see `adbc-driver-manager-test`. Is this normal or am I misunderstanding something?

I've stumbled upon this while debugging an issue with the Rust implementation and it might be related to using the SQLite driver through the driver manager on Windows (though I can't reproduce the issue on my local Windows 11...)

### How can we reproduce the bug?
