Add reference to Easypanel template

[Supernova3339]

This PR adds reference to the easypanel template of Servas, to make deployment easier and more accessable. The template uses the official image, and uses a MariaDB database for deployment. It is possible to adjust storage, environment variables, even code!

This PR adds

• An update to the README.md providing a reference to the Easypanel template

Reason why you should merge

• Adds another method of deployment
• Easier method, less experience needed
• Port forwarding taken care of
• Easypanel doesn't cost anything for essential core features. You could have 1000 deployments of Servas and not pay anything!

Thank you. Since I do not know this service, I do not want a reference in the README.
