Fix `*interface{}` in `patch_operation_info.go`

[grokify]

*interface{} isn't valid in patch_operation_info.go.

The following error is encountered with 2.3.1:

Error when using struct:

cannot use "github.com/grokify/go-ringcentral/client".UserInfo literal \
(type "github.com/grokify/go-ringcentral/client".UserInfo) as type *interface {} \
in field value: *interface {} is pointer to interface, not interface

Error when using struct pointer:

cannot use "github.com/grokify/go-ringcentral/client".UserInfo literal \
(type *"github.com/grokify/go-ringcentral/client".UserInfo) as type *interface {} \
in field value: *interface {} is pointer to interface, not interface

OpenAPI/Swagger 2.0 Spec is as follows:

    "PatchOperationInfo": {
      "type": "object",
      "required": [
        "op"
      ],
      "properties": {
        "op": {
          "type": "string",
          "enum": [
            "add",
            "replace",
            "remove"
          ]
        },
        "path": {
          "type": "string"
        },
        "value": {
          "type": "object",
          "description": "corresponding 'value' of that field specified by 'path'"
        }
      }
    },

Update to remove the * pointer.
