conda on macos with Python 3.10 seems broken (and it's now the default)

[Cadair]

I have modified our tests to avoid this issue but we should investigate.

Build here: https://dev.azure.com/OpenAstronomy/azure-pipelines-templates/_build/results?buildId=516&view=logs&j=8c100718-7b30-5727-c5dc-a891c555a9cc&t=b3c64b5b-c20a-5492-7af8-1101bd91adb4&l=79

Running conda jobs without a Python prefix will put python= in the conda install command. I doubt that is the issue as it should have failed before solving the env. The conda Python build it downloads does have a /lib/py3.1 however it's a symbolic link (probably for code which isn't expecting 2 digits in the minor version). Maybe Azure doesn't allow the symlink? Not at computer right now but can take a look tomorrow. Probably an upstream issue though.
