macOS-13 CI test issues

[Nick Herringer]

Hello all,

I'm trying to prepare a PLUMED module for PR, but I'm having some trouble with the conda (macos-13) CI test (specifically the Install Conda portion of the test) when I push to github. I wasn't having any issues with this before September but I now get the following error:

LibMambaUnsatisfiableError: Encountered problems while solving:

- package anaconda-client-1.6.11-py27_0 requires python >=2.7,<2.8.0a0, but none of the providers can be installed

Could not solve for environment specs

└─ pin on python 3.13.* =* * is not installable because it requires

└─ python =3.13 *, which conflicts with any installable versions previously reported.

Pins seem to be involved in the conflict. Currently pinned specs:

- python=3.13

I've been trying to troubleshoot it for days (I can't find python=3.13 pinned anywhere and I've tried different versions of python as well as anaconda-client) but I haven't gotten it to work. Any insight about the issue would be much appreciated.

Thanks,

Nick
