[Bug Report][3.0.0-beta.13] VList event update:selected data typed as array of string no matter the item value type

[aentwist]

Environment

Vuetify Version: 3.0.0-beta.13
Last working version: 2.6.6
Vue Version: 3.2.40
Browsers: Firefox 91.0
OS: Linux x86_64

Steps to reproduce

As in the title, even if a custom value is used for selected items, the expected event data is an array of string. This typing is defined here.

For example,

<VList v-model:selected="selectedBooks" select-strategy="leaf">
  <VListItem
    v-for="book in books"
    :key="book.id"
    :value="book"
    :title="book.title"
    :subtitle="book.author"
   />
</VList>

(property) selected?: string[] | undefined
Type 'Book[]' is not assignable to type 'string[]'.

In Vuetify 2, v-list-item-group typed the data as any[]. Note also that the selected prop appears to take any[] (needs verification).

Maybe if the goal was to improve upon any, could a generic somehow be used here? Either way, any is better than string here.

Expected Behavior

No type error

Actual Behavior

Type error (still works)
