Hello VSCode Team,

I have noticed some issues with the group policy setting for allowed extensions.

- The field for entering it is too small and as such doesn't allow long strings
- It's unintuitive to edit the entries since the JSON should be a single line without any new lines and also has a length limitation
- Please consider an alternative UI for the group policy so that it's easier to add the entries. 
 
The other issues have been documented below. Please let me know if you need further details.

Steps to Reproduce:

1. Install remote ssh extension and other extensions from microsoft or github publisher 
2. Add the following entry to the group policy for allowed extensions `{ "github": true, "microsoft": true }`
3.  Now the remote ssh editing icon disappears from the side bar, see image below, basically the publisher field is not working as expected

4. Add the extensions with the correct extension id to the group policy, then apply with `gpupdate` , the extensions are enabled again
5. Use a  a very long list of allowed extensions like in the example below, the group policy field cuts off after a specific length and the resulting entry is invalid and as such is ignored by the group policy
