> Enforce one way to escape `${` in template literals

To write a literal `${` in a template literal you need to escape it, and three spellings work: a backslash before the `$`, before the `{`, or before both. All three give the same string. This rule keeps the first one, `\${`, so an escaped placeholder looks the same everywhere.

Tagged templates aren't checked, because a tag can read the raw text.

`--fix` rewrites the escape.

## Configure
