Miniconda info on conda-forge.org main page needs correcting

### Where should the content be changed?

conda-forge.org

### What should be changed?

On the main conda-forge.org page, the paragraph on Miniforge contains the sentence "Unlike Miniconda, these support ARMv8 64-bit (formally known as aarch64)." Miniconda does support aarch64. It's probably not compatible with conda-forge specifically, but it does support it, so that sentence should likely be removed.

### Additional information

See https://docs.conda.io/en/latest/miniconda.html for info on the Miniconda system architecture requirements.
