[BUG] [docstrings] [vscode] Weird behaviour when using double backslashes with newline separators and inserting mojo code

[martinvuyk]

Bug description

This underlines the last 3 mojo examples in red and says unterminated backtick identifier though they still generate correctly when hovering over the function name

    fn split[
        maxsplit: Int = -1
    ](self, owned delimiter: String = "") -> List[String]:
        """Split the string by a delimiter. This defaults to universal
        newlines [just as Python](https://docs.python.org/3/library/stdtypes.html).
 
        Parameters:
            maxsplit: The maximum amount of items to split from String.
                Defaults to unlimited.
 
        Args:
            delimiter: The string to split on.
 
        Returns:
            A List of Strings containing the input split by the delimiter.
 
        Examples:
 
        Splitting a space:
 
        ```mojo
        var s = String("hello world").split(" ") # ["hello", "world"]
        ```

        Splitting adjacent delimiters:

        ```mojo
        var s = String("hello,,world").split(",") # ["hello", "", "world"]
        ```
 
        Splitting adjacent universal newlines:
 
        ```mojo
        var s = String("hello \\t\\n\\r\\f\\v\\x1c\\x1e\\x85world").split() # ["hello", "world"]
        ```

        Splitting with maxsplit:

        ```mojo
        var s = String("1,2,3").split[maxsplit=1](",") # ['1', '2,3']
        ```
 
        Splitting an empty string or filled with whitespaces:
 
        ```mojo
        var s = String(" ").split() # []
        var s = String("").split() # []
        ```

        Splitting a string full of the delimiter:

        ```mojo
        var s = String(",,,").split(",") # ["", "", "", ""]
        ```
        .
        """
        ....

Steps to reproduce

• Include relevant code snippet or link to code that did not work as expected.
• If applicable, add screenshots to help explain the problem.
• If using the Playground, name the pre-existing notebook that failed and the steps that led to failure.
• Include anything else that might help us debug the issue.
