[masesdevelopers]

          Docker scout reports some vulnerabilities should be solved:

Meanwhile the base image shall be changed to avoid the usage of the Debian OS. See https://mcr.microsoft.com/en-us/product/dotnet/runtime/tags and check the right variant to use; or surf https://github.com/dotnet/dotnet-docker/blob/main/documentation/ubuntu-chiseled.md for other info.

Extract Docker publish and adds a workflow which runs on:

• after the release workflow
• after a manual trigger

Add disclaimer on licenses used from Docker base runtime image referring to https://github.com/microsoft/containerregistry/blob/39d2e014897475ef6cdb08e29c08645f53f0dc93/legal/Container-Images-Legal-Notice.md and https://github.com/microsoft/containerregistry/blob/39d2e014897475ef6cdb08e29c08645f53f0dc93/legal/Linux-Legal-Metadata.md.
In this way we are able to redirect them to the runtime image of .NET used to build the final image.
