miniforge.sh: line 1: Not: command not found

Hello! Thanks for creating these devcontainer-features. I've been running into an issue when trying to use the miniforge feature. I was wondering if anyone has an idea of what might be happening?

	// Or use a Dockerfile or Docker Compose file. More info: https://containers.dev/guide/dockerfile

	},
}

Maybe they changed the installer URL, I'll have a look when I have time.

As a workaround, you can use the version option to specify a version before the URL scheme was changed, which should work.

thanks! your suggestion worked!

	"features": {
		"ghcr.io/rocker-org/devcontainer-features/miniforge:2": {
			"version": "26.1.0-0"
		}
	},

Looking through the code, it seems like it's just failing when it tries to download the URL here:

devcontainer-features/src/miniforge/install.sh

Lines 104 to 116 in 27e62e2

	install_miniforge() {
	local variant=$1
	local version=$2
	local conda_dir=$3
	local download_url
	download_url="https://github.com/conda-forge/miniforge/releases/download/${version}/${variant}-${version}-Linux-$(uname -m).sh"
	check_packages curl ca-certificates
	mkdir -p /tmp/miniforge
	pushd /tmp/miniforge
	curl -sLo miniforge.sh "${download_url}"
	chmod +x miniforge.sh
	/bin/bash miniforge.sh -b -p "${conda_dir}"

Unfortunately, the latest release of miniforge (v26.1.1-0) was published as a pre-release without any of the usual assets, so install.sh is unable to download .sh files from it.

I created #275 in an attempt to remedy this
