macOS > 12 images do not have miniconda installed

[s-weigand]

Description

I recently got an issue that setting up conda fails on macos-latest. This is related to macos-latest changing form macos-12 to macos-14, where the macos-13 and macos-14 images do not have miniconda preinstalled.

macos-12 Packer template

macos-13 Packer template

macos-14 Packer template

If this is desired I would give a PR a shot where I would add the miniconda installation to the newer macos versions and make install-miniconda.sh compatible with arm64.

Is it regression?

N/A

Expected behavior

Miniconda is installed and the CONDA environment variable pointing to the root installation folder is set as it was in macos-12.

Actual behavior

Miniconda is not installed and the CONDA environment variable is not set.
