Review update-task-version feature when latest version adds an parameters with a default

[tcompa]

Ref fractal-analytics-platform/fractal-server#2349.
We should review this behavior also in fractal-web.

Also note that the request body is now required, as of the first backend version after 2.13.1 - be it 2.13.2 or 2.14.0.

I tested the new version in #731 as follows.

Create a v1 task with JSON schema

{
  "additionalProperties": false,
  "properties": {
    "image_dir": {
      "description": "Image where the raw images are",
      "title": "Image Dir",
      "type": "string"
    },
    "num_images": {
      "default": 2,
      "description": "Number of images that this dummy task will produce.",
      "title": "Num Images",
      "type": "integer"
    },
    "zarr_dir": {
      "description": "description",
      "title": "Zarr Dir",
      "type": "string"
    },
    "zarr_urls": {
      "description": "description",
      "items": {
        "type": "string"
      },
      "title": "Zarr Urls",
      "type": "array"
    }
  },
  "required": [
    "zarr_urls",
    "zarr_dir",
    "image_dir"
  ],
  "title": "CreateCellvoyagerOmeZarr",
  "type": "object"
}

Create the v2 of the same task, with an additional darkfield: bool = True argument - and with JSON schema

{
  "additionalProperties": false,
  "properties": {
    "darkfield": {
      "default": true,
      "description": "xxx",
      "title": "Darkfield",
      "type": "boolean"
    },
    "image_dir": {
      "description": "Image where the raw images are",
      "title": "Image Dir",
      "type": "string"
    },
    "num_images": {
      "default": 2,
      "description": "Number of images that this dummy task will produce.",
      "title": "Num Images",
      "type": "integer"
    },
    "zarr_dir": {
      "description": "description",
      "title": "Zarr Dir",
      "type": "string"
    },
    "zarr_urls": {
      "description": "description",
      "items": {
        "type": "string"
      },
      "title": "Zarr Urls",
      "type": "array"
    }
  },
  "required": [
    "zarr_urls",
    "zarr_dir",
    "image_dir"
  ],
  "title": "CreateCellvoyagerOmeZarr",
  "type": "object"
}

Add task v1 to a workflow

Update to v2

Export arguments

{
  "args_parallel": null,
  "args_non_parallel": {
    "darkfield": true,
    "num_images": 2,
    "image_dir": "/something"
  }
}

I also added an optional argument, and observed nothing unexpected:
