Implement form page for CrudModule

[brunomous]

Implement new page as container variation for the CrudModule. To use the page, the prop formContainerVariation should be passed with page as value, and the following routes should be added to the Router instance on the child project, with isFormPage prop as true:

<Resource
  id="/user/new"
  name="Create User"
  showDrawerItem={false}
  module={{
    createFormProps: {
      formSchema: userModule.createFormProps?.formSchema,
      formUiSchema: userModule.createFormProps?.formUiSchema,
    },
  }}
  isFormPage
/>

<Resource
  id="/user/edit/:id"
  name="Edit User"
  showDrawerItem={false}
  module={{
    editFormProps: {
      formSchema: userModule.editFormProps?.formSchema,
      formUiSchema: userModule.editFormProps?.formUiSchema,
    },
  }}
  isFormPage
/>

<Resource
  id="/user/details/:id"
  name="View User"
  showDrawerItem={false}
  module={{
    detailsFormProps: {
      formSchema: userModule.detailsFormProps?.formSchema,
      formUiSchema: userModule.detailsFormProps?.formUiSchema,
    },
  }}
  isFormPage
/>

The /{resource}/new, /{resource}/edit/:id and /{resource}/details/:id are required for the workflow to perform correctly.
