(Improvement) Guidance 2022.2.1.9 17/10/2022: Keep comments when modifying the .json files

[vvdb-architecture]

Comments in appsettings.[Environment].json are not kept when certain operations are executed.
Steps to reproduce:

• Edit appsettings.Localhost.json in your service, and add a comment. For example

 /* Review these memory settings after adding feature whatchamacallit */
  "Memory.Settings": {
    "SizeLimitInMegaBytes": "10"
  },

• Right click on the service host, and select "Add a service account".
• View the appsettings.Localhost.json file: the service account has been added but the comment has disappeared.
