[Docs Fix] Incorrect note about lifecycle hooks in reused components — onUpdated still fires

[LupinThe1st]

Reproduction

https://router.vuejs.org/guide/essentials/dynamic-matching.html#Reacting-to-Params-Changes

Steps to reproduce the bug

1. Create a Vue 3 + Vue Router project.
2. Define a dynamic route (/users/:name) and map it to a component (User.vue)
3. In User.vue, add the onUpdated hook to log changes
4. Navigate from /users/johnny to /users/jolyne.
5. Observe that onUpdated is called despite the docs claiming that the lifecycle hooks of the component will not be called.

Expected behavior

The documentation suggests that no lifecycle hooks (including onUpdated) should be called when reusing a component instance during route navigation (e.g., /users/johnny → /users/jolyne).

Actual behavior

onUpdated is triggered when route params change

Additional information

Even if User.vue has an empty (no rendered content), the onUpdated hook will still be triggered during the navigation steps described above.
