bcrs-shared-components: upgrade to Vue3 / Vuetify3

[severinbeauvais]

See also #14882.

Before any UIs can be upgraded to Vue3, the 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.

Here's a blog I found that might be useful for updating/refactoring this repo: https://blog.logrocket.com/setting-up-monorepo-lerna-typescript/

Here are the lint errors that should be saved along the way: lint.log

Here is the eslint config I used: .eslintrc.js
