Is your feature request related to a problem? Please describe.
Currently Github Actions does not work, ssl cert.pem and key.pem is not pushed to repository due to security reasons. Therefor when making changes to the repository the Docker Package needs to be updated manually.

Describe the solution you'd like
Integrating Let's Encrypt will make it both easier for repository moderators and for the user using this template. No need to manually download a certificate and add to correct folders etc.

Describe alternatives you've considered
From a user perspective this should at least be documented on how to add your own certificate to the template.
