Is your feature request related to a problem? Please describe.
JSON schema is a widely used and understood format for defining the shape of data structures. Existing applications already make use of it and have schemas written for entities. It would make adoption of orama search easier if a database could be created using a json schema rather than only the custom schema DDL that orama currently offers.

Describe the solution you'd like

import { create } from '@orama/orama'
 
const movieDB = await create({
  jsonschema: {
    type: 'object',
    properties: {
      title: { type: 'string' },
      director: { type: 'string' },
      plot: { type: 'string' },
      year: { type: 'number' },
      isFavorite: { type: 'boolean' }
    },
    required: [ 'title', 'director', 'plot', 'year', 'isFavorite' ]
  },
})

Describe alternatives you've considered
Writing my own custom script to try and convert my existing json schemas into oramas schema format.

Additional context
JSON schema website: https://json-schema.org/
There is widely available tooling available for json schema, and generating json schema from almost any language.
Consider the case of a very complex ecommerce site with a Golang backend, all the entities are defined in Go structs and stored in Mongodb. They want frontend in-memory search. They would need to rewrite all their schemas in oramas format to make the fields searchable.
With my feature request, they could simply run their Go structs through a jsonschema generator such as https://github.com/invopop/jsonschema and then all fields are instantly searchable with no manual schema writing.

Additional benefit
Not the main feature request but a side benefit is that typescript types can be inferred from jsonschema, meaning the database could be automatically typed after being created with a jsonschema, so insert, update and search could all have the correct types without being specified by the user, since it gets inferred from the jsonschema.
