Vue3 upgrade: try to use new Vuetify 3 date picker

[severinbeauvais]

For a while, Vuetify 3 did not include a Date Picker component, so some external solutions were used (eg, see #18526).

Now, Vuetify 3 includes a Date Picker -> https://vuetifyjs.com/en/components/date-pickers/#usage

This ticket is to investigate whether this Date Picker can be used in shared component DatePicker.vue (or whether we should use the external solution).

To do:

• import new libraries (Vue 3, Vuetify 3) into shared component DatePicker
• try to use new Date Picker in the shared component
• update Storybook file
• update unit tests
