[zod] Add support for extra issue keys in errors

[ilyichv]

Is your feature request related to a problem? Please describe.
It would be nice to have the whole context of the issue. Let's take for example the following code in a zod's superRefine

   ctx.addIssue({
      code: 'custom',
      path: ['code'],
      minimum: serial_number_min_length,
      message: 'min_serial_number',
    });

If I take a look to the form state, under code

{
    "message": "min_serial_number",
    "type": "",
    "ref": {}
}

Loosing minimum key which may be useful for some use cases.

Describe the solution you'd like
Maybe adding a dedicated key for zod issues to the result would be the solution. Resulting in:

{
    "message": "min_serial_number",
    "type": "",
    "ref": {},
    "zodIssue": <rawIssue>
}

Describe alternatives you've considered
Currently there is no workaround except for customizing the message directly which may not be the best thing to do for some use cases. (eg. message is used as i18n key) to be translated later on.
