No longer updating the command line

[GrahamTheCoder]

Shortly after the migration to Github actions, something changed which broke the automated tests covering the command line.
This may indicate that the build of the command line would also be broken for newer versions of dotnet/msbuild, or that the problem is unique to the tests. I don't have time to investigate what's changed and how to fix it at this time, so I'm stopping deploying new versions of the command line in the hope that the old one will continue to work.

Some manual testing of the command line with latest versions of dotnet would be a good first port of call for understanding this issue.

On a machine where the tests fail (whole solution tests - currently skipped):

• Check if the currently released commandline can convert the solution used in the tests
• Check if a newly compiled commandline can convert the solution used in the tests

Tests work now so should be fine to ship this again
