Running Task commands, will delete comments from tasks.json file

[elahehrashedi]

• VSCode Version: 1.48.2 and 1.49.0-insider
• OS Version: Win64

Steps to Reproduce:

1. configure a few tasks in tasks.json file.
2. add some comments to the tasks.json file.
3. Run "Tasks: Configure default build task"
4. Change the default task
5. Now you will see that the comments are removed from tasks.json file.

The same issue will happen when running any Tasks command that needs to modify the tasks.json file (e.g. "Task: configure task", ...)

@sean-mcmanus Should I close this?

We solved this issue in C/C++ extension by using the comment-json library.

Yeah, you could close it. I think the VS Code team would close it as a duplicate.
