Debug watch does not format list items using the format specifiers

## Issue Description ##

As per #2713 you can use format specifiers ([full list](https://github.com/MicrosoftDocs/visualstudio-docs/blob/master/docs/debugger/format-specifiers-in-csharp.md#format-specifiers)) on watch variables. But it does not work as expected on lists/arrays.

## Steps to Reproduce ##

Watch a byte array in vscode c# omnisharp

## Expected Behavior ##
The items should show as hex values

## Actual Behavior ##
As you can see I added the `,h` format specifier but only the main variable description changes, not the items.

## Environment information ##

**VSCode version**: 1.61.0
**C# Extension**: 1.23.16
