Example from earlier today: https://github.com/shannon-lab/zapdos/actions/runs/6630597542/job/18012311259

We see the action install the specified environment:

  /usr/share/miniconda3/condabin/mamba env update --name zapdos --file scripts/conda_environment.yml
  
  
  Looking for: ['python=3.10', 'moose-dev']
  
  
  Transaction
  
    Prefix: /usr/share/miniconda3/envs/zapdos
  
    Updating specs:
  
     - python=3.10
     - moose-dev

which then leads to very out-of-date packages:

This approach was tested and confirmed to work in the following action run: https://github.com/shannon-lab/zapdos/actions/runs/6631281085

With that, @csdechant could you formally review this change? Thanks!
