Describe the bug

When trying to deploy an application with service_bindings, the provider fails with the error: Value Conversion Error

Full Log

 Error: Value Conversion Error
│ 
│   with cloudfoundry_app.http-bin-server,
│   on main.tf line 11, in resource "cloudfoundry_app" "http-bin-server":
│   11: resource "cloudfoundry_app" "http-bin-server" {
│ 
│ An unexpected error was encountered trying to build a value. This is always an error in the provider. Please report

│ don't know how to reflect tftypes.String into interface {}

Expected Behavior

The parameters are parsed successfully.

Steps To Reproduce

Execute terraform apply

Your Terraform Configuration

resource "cloudfoundry_app" "http-bin-server" {
  name         = "tf-test-do-not-delete-http-bin"
  space_name   = "Space-Name"
  org_name     = "Org-Name"
  docker_image = "kennethreitz/httpbin"

  no_route = true
  service_bindings = [
    {
      service_instance : "xsuaa_svc"
      params = {
        role = "Token_Exchange"
      }
    }
  ]
 }

Additional context

The error is thrown at mapAppValuesToType.

Seems like serviceManifest.Parameters expects map[string]interface{} but gets string instead

Note: If this conversion error is somehow bypassed for e.g #101 then the app gets created with the service bindings correctly bound
