doc: Usage `.path` in HTTPEvent is not correct

[Nayeem-4-You]

https://nitro.build/docs/lifecycle#request-hook

The example shown here uses:

`console.log(`Incoming request on ${event.path}`);

in:

import { definePlugin } from "nitro";

export default definePlugin((nitroApp) => {
  nitroApp.hooks.hook("request", (event) => {
    console.log(`Incoming request on ${event.path}`);
  });
});

The event here is an HTTPEvent not H3Event, so there is no path property in this event.
