* Initial $shell internal-api - Add ModalManager and SlideInPanelManager components
* Use Teleport for Modal and SlideIn managers - Add unit tests
Unit test fix
* Add focus trap and tabindex to Modal and SlideIn managers
* Correct file naming and small TS issues
Correct TS related issues
* Manual replacement of :is on standard HTML tags
* Add missing required in the code dependencies
* Correct SCSS import
* Correct test file naming
* Correct typo in markup
* Use alias for types import
Update paths in `shell/tsconfig.paths.json` to include "@components/*" alias that maps to "../pkg/rancher-components/src/components/*". Typescript was unable to properly locate components using the `@components` alias because this path was not defined.
Add declarations to support our i18n plugin to `shell/types/vue-shim.d.ts` so that `this.t()` and the `t` component can be recognized in components utilizing `defineComponent`.
