Disallow template literal placeholder syntax in regular strings.
ECMAScript 6 allows programmers to create strings containing variable or expressions using template literals,
instead of string concatenation, by writing expressions like ${variable} between two backtick quotes (`).
It can be easy to use the wrong quotes when wanting to use template literals, by writing "${variable}",
and end up with the literal value "${variable}" instead of a string containing the value of the injected expressions.
