Raw string literals have very poor support

[just-ero]

Environment Data

VS Code version: 1.99.3 C# Extension version: 2.74.24

Steps to Reproduce

1. Attempt to declare a raw string literal anywhere by typing its opening 3 (or more) quotation marks:

   string s = """|
   

   Where | is the cursor position.

Expected Behavior

The corresponding 3 quotation marks should be inserted on the other side of the cursor.
Inserting a new line then formats the quotation marks like below:

string s = """
    |
    """

Where | is the cursor position.

Actual Behavior

The corresponding 3 quotation marks are not inserted.
Inserting a new line results in the cursor being on the same level as the declaration:

string s = """
|

Where | is the cursor position.
