ci: fixing issues around Standards check

[michalChrobot]

Purpose of this PR

This PR fixes the issues we had with standards check job which are

1. Editor was not pinned which means whenever new version of 6000.3 got released you could get random manifest changes. I had to align this to testproject ProjectVersion so I used 6000.0.72f1 editor (this will be different for develop-3.x.x)
2. Dotnet version may vary depending on which image was used for the job. This should be quite stable as we pin the image directly but I improved logging and pointed to this issue (so local results may not always be the same as CI due to different dotnet version)
3. I unified the approach for package-lock.json handling with the one we have on develop-3.x.x branch (added to .gitignore and removed from test projects)
4. I unified editors for all our test projects here (to use 6000.0.72f1 which is latest patch of the minimal supported one)
