Part of #33724, and extension to #34405.
This file's contents are used to call the endpoint:
```
/layouts/{layoutId}/pages/{pageId}?applicationId={applicationId}
```
But this endpoint accepts request payload as `LayoutUpdateDTO`, which
only has one single field, `dsl`, and nothing else.
But the way we use this JSON, is that we're sending the body as this:
```json
{
"widgetName": "MainContainer",
"backgroundColor": "none",
"rightColumn": 1296,
"snapColumns": 64,
"detachFromLayout": true,
"widgetId": "0",
"topRow": 0,
"bottomRow": 440,
"containerStyle": "none",
"snapRows": 125,
"parentRowSpace": 1,
"type": "CANVAS_WIDGET",
"canExtend": true,
"version": 47,
"minHeight": 420,
"parentColumnSpace": 1,
"dynamicBindingPathList": [],
"leftColumn": 0,
"children": []
}
```
Not as this:
```json
{
"dsl": {
"widgetName": "MainContainer",
"backgroundColor": "none",
"rightColumn": 1296,
"snapColumns": 64,
"detachFromLayout": true,
"widgetId": "0",
"topRow": 0,
"bottomRow": 440,
"containerStyle": "none",
"snapRows": 125,
"parentRowSpace": 1,
"type": "CANVAS_WIDGET",
"canExtend": true,
"version": 47,
"minHeight": 420,
"parentColumnSpace": 1,
"dynamicBindingPathList": [],
"leftColumn": 0,
"children": []
}
}
```
Which means that we aren't sending anything useful.
