docs: fix script description

```suggestion
In the request body, provide the script properties to update.
```
This is my new pattern. Eventually, I plan to append an statement (with redoc-cli) that introduces the properties that can be set, like in YouTube docs--"You can set the following properties for this resource:"

Review the request-body description discussed in pull request #444 and locate the corresponding script resource in the OpenAPI specification. Update the description to clarify that the request body contains script properties to update, then verify the rendered documentation with redoc-cli.
