    doc: Correct jsonpath string literal escapes description
    
    The paragraph describing the JavaScript string literals allowed in
    jsonpath expressions unnecessarily mentions JSON by erroneously
    listing \v as allowed by JSON and mentioning the \xNN and \u{N...}
    backslash escapes as deviations from JSON when in fact both are
    accepted by ECMAScript/JavaScript.  Fix this by only referring to
    JavaScript.
