RCS0056 with raw strings issue

[prezaei]

The following block, triggers RCS0056:

        var a = $$"""
            - “Hey, {{userContext.User.FirstName}}! test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test .”
            hey line 2.
            """;

This also triggers it:

        var a = $"""
            - “Hey, { "name" } test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test .”
            hey line 2.
            """;

but this doesn't:

        var a = """
            - “Hey, test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test test .”
            hey line 2.
            """;
