Helm chart for Wallos

[vide]

Hello! I created an Helm chart for Wallos so I can easily install it in my homelab k8s, since I'm migrating it from a docker-compose installation. You can find it here: https://github.com/vide/wallos-charts

If you want, I could open a PR to add it in the README as an installation method. WDYT?

Thanks!
