docs: Wraps a {@link JsExpr} that could have incorrect precedence in parens.
  
  <p>The JsExpr constructor is inherently error-prone. It allows callers to pass a precedence
  unrelated to the topmost operator in the text string. While JsExprs created in the Soy codebase
  can be audited, JsExprs are also returned by {@link SoyJsSrcFunction functions} and {@link
  SoyJsSrcPrintDirective print directives} owned by others. This method should be used to wrap
  the results of those plugins.
