.NET 7 support

[mbp]

Running "grate" within a Docker container mcr.microsoft.com/dotnet/runtime:7.0, outputs the following error message:

You must install or update .NET to run this application.
App: /opt/bin/grate
Architecture: x64
Framework: 'Microsoft.NETCore.App', version '6.0.0' (x64)
.NET location: /usr/share/dotnet

The following frameworks were found:
7.0.0 at [/usr/share/dotnet/shared/Microsoft.NETCore.App]

Is it possible to support system where only .NET 7 is installed?
