Data strings don't work in preview plugin

[krystof-k]

I guess the plugin is not part of this repo, so if this isn't the right place to report it please tell me where is.

Using data strings for operations in sandboxes using stripe preview doesn't work:

stripe preview use "Kryštof dev"
✔ Remaining on Kryštof dev. This is a sandbox, no live data will be affected.

stripe preview products list
Operating in Kryštof dev (wksp_test_6R3…)...
{
  "object": "list",
  "data": [],
  "has_more": false,
  "url": "/v1/products"
}

stripe preview products create -d 'name=test'
Operating in Kryštof dev (wksp_test_6R3…)...
Error: invalid character 'a' in literal null (expecting 'u')

Using option syntax it works (but that is not viable for nested objects):

stripe preview products create --name test   
Operating in Kryštof dev (wksp_test_6R3…)...
{
  "id": "prod_QlR97hKZph6ct6",
  "object": "product",
 …
}

Without preview it works:

stripe products create -d 'name=test'        
{
  "id": "prod_QlR88YgZONPoFR",
  "object": "product",
  …
}

macOS, Stripe CLI version 1.21.3.

Seems this is the same bug as #1240
