Codecov not being submitted

[cjdoris]

Coverage is not being submitted to codecov as expected (see any recent test runs). I assume there are some settings needing changed but I don't have the creds for that.

@stevengj can you take a look please? This affects PythonCall, CondaPkg and MicroMamba.

e.g. https://github.com/JuliaPy/PythonCall.jl/actions/runs/6175189782/job/16761502648#step:8:31

Works now.
