'Mambaforge' variants are now equivalent to 'Miniforge3'. In the future, we will ignore with a warning and use 'Miniforge3'. Eventually, using 'Mambaforge' will throw an error. Please change to 'Miniforge3' at your earliest convenience.

The 'defaults' channel might have been added implicitly. If this is intentional, add 'defaults' to the 'channels' list. Otherwise, consider setting 'conda-remove-defaults' to 'true'.
