build(deps): make vue@3 and vue-router@5 peer dependencies

[ShGKme]

☑️ Resolves

• Alternative for build(deps): allow vue-router ^4.6.4 or ^5.0.2 #8155
• Makes Vue and Vue-Router required to be on the last major version in apps using the library
• I'd merge it only after the final Nextcloud 33 release just in case there is a problem with vue-router@5

🏁 Checklist

• ⛑️ Tests are included or are not applicable
• 📘 Component documentation has been extended, updated or is not applicable
• 2️⃣ Backport to stable8 for maintained Vue 2 version or not applicable
