Expected requirements for contribution should be included in VSCode settings to make it easier

Requirements like line length and other similar settings that can be added to the settings.json file under the .vscode folder should be so that contributors automatically benefit from those settings.

"files.defaultLanguage": "powershell",
"[powershell]": {
  "editor.rulers": [ 120 ]
},
"[markdown]": {
  "editor.rulers": [ 120 ]
}

We could also add a extensions.json that suggest adding the extension markdownlint that is used for validating markdown in HQRM tests.
