[release/9.1] Fix arg annotations when running in IDE mode

[github-actions]

Backport of #7711 to release/9.1

/cc @danmoseley @JamesNK

Customer Impact

.NET projects can be configured with command line args in their launch profile and in the app host. The dashboard displays them to the user.

There are two modes of running .NET projects: IDE and process. The dashboard is displaying args to the user incorrectly in IDE mode. It combines the args from the profile and app host, but it should be using only the app host args if present, then falling back to the profile args.

The impact here is user confusion about the args they see in the dashboard vs the args that project is run with.

Testing

Unit tests and manual testing.

Args here - --port 7071 - correctly aren't duplicated:

Risk

Medium. The PR changes how args are calculated for .NET projects. It's important code to get right.

Regression?

No. In 9.0 args were never shown for .NET projects.
