Get started with Juju tutorial unable to run on ARM architecture

Issue: The self-signed-certificate app has no matching constraint for arch=arm64.

Steps to reproduce:

1. Install Multipass for MacOS
2. Create VM multipass launch --cpus 4 --memory 8G --disk 50G --name my-juju-vm charm-dev
3. Boostrap controller juju bootstrap microk8s 34microk8s
4. Create model: juju add-model chat
5. Deploy app: juju deploy self-signed-certificates

Deploying this app on arm64 causes it to fail. When running juju deploy self-signed-certificates --constraints "arch=arm64", the deploy fails saying there is no match for this constraint.
