bcrs-shared-components: upgrade to Vue3 / Vuetify3

See also #14882.

Before any UIs can be upgraded to Vue3, the [BCRS Shared Components](https://github.com/bcgov/bcrs-shared-components) (and interfaces, enums, etc) need to be upgraded to Vue3. This includes:
- [x] upgrade repo to Vue3 (main package file, dependencies)
- [x] upgrade Storybook to Vue3
- [ ] upgrade all components to Vue3/Vuetify 3, including stories and unit tests - **in progress - see tickets below**
- [ ] anything else I didn't think of

Each exported component (and interfaces, enums, etc) should be bumped to their next major version. The current versions can be used by Vue2 UIs, and Vue3 UIs would use the new versions.
