Cannot install latest version using `micromamba` on Windows

[a-ws-m]

Description

Creating a new environment with micromamba create -n freud_test freud on Windows will only install Python 3.8 and Freud 2.2.0. Pinning a later Python version reveals an issue with the python_abi requirement.

Steps to Reproduce

micromamba create -n freud_test freud "python=3.12"

I am not able to reproduce this problem. Did you configure micromamba without conda-forge? Your .condarc (or .mambarc) file should contain:

channels:
  - conda-forge
  - nodefaults
channel_priority: strict

>micromamba create -n freud_test freud python=3.12
  Updating specs:

   - freud
   - python=3.12

Thank you, that fixed it for me! I didn't realise micromamba didn't come with those channel priorities as default.
