Replace the directives in the RunJS codeblock with a more generic form

[eoureo]

Would the alternatives be better?

Current

```js RunJS:{n:"group/name", t:"s"}
```

```js RunJS:"group/name"
```

/**
 * @RunJS {n:"group/name", t:"s"}
 *
 */

/**
 * @RunJS "group/name"
 *
 */

Alternatives

```js RunJS="{n:'group/name', t:'s'}"
```

```js RunJS="group/name"
```

/**
 * @RunJS {n:'group/name', t:'s'}
 *
 */

/**
 * @RunJS group/name
 *
 */
