📚 Description

Improves dx. Provides an example of how to make a component reusable. Made changes to the passed component types to not be tied to a specific data model, now the type is based on a generic type. Extended tasks.json for use in the example, the data for tasks.json is taken from DummyJSON. Added a user to the schema for tasks.json. Fixed filter-function type incompatibility in examples/tasks/components/DataTableFacetedFilter.vue
