Universal call to mamba fails

Hello,

Is this expected that the universal call to `mamba -- version` in example 6 fails on Windows?

Example here: https://github.com/conda-incubator/setup-miniconda/actions/runs/12642945396/job/35228139155
Output is:
```
Microsoft Windows [Version 10.0.20348.2966]
(c) Microsoft Corporation. All rights reserved.

D:\a\setup-miniconda\setup-miniconda>
```

instead of `2.0.5`

Regards
