Support snap based Linux system

I'm on a macos host. Running vscode in remote host. Within a vm, then running opening the dev container within the remote host.

Happy to help in anyway, just let me know

You can create an identical virtual machine using multipass and the following cloud init
```
users:
- default
- name: vmuser
sudo: ALL=(ALL) NOPASSWD:ALL
ssh_authorized_keys:
- ssh-ed25519 -----
groups:
- docker
snap:
commands:
- [install, docker]
runcmd:
- adduser vmuser docker
- reboot
```

```
