generate-typescript-typedefs sets type string for number field values

[m4w]

Current behavior:
We use the generate-typescript-typedefs command to generate our types. But we noticed an issue: When we choose the field type 'number' in storyblok the generated type will be string, which is very unexpected, since this is a very easy type.

Expected behavior:
The type of a field-type number should be number as well.

Steps to reproduce:
Create a new Storyblok Block, with one field type number. Save that block.
Use the generate-typescript-typedefs command to generate the types for this new block. Notice that the new field-type has the type string instead of number.

An example components.json schema:

{
  "name": "some_block",
  "display_name": "Some Block",
  "schema": {
    "columns": {
      "type": "number",
      "pos": 0,
      "min_value": 2,
      "max_value": 3,
      "default_value": "2",
      "steps": 1
    }
  }
}

And the related typings:

export interface SomeBlockStoryblok {
  columns?: string
}
