Add an opportunity to load entity in an embedded form

[voodooism]

I encountered a problem where the embedded form entity DTO does not have an instance of the entity. Specifically, this issue occurs in the EasyCorp\Bundle\EasyAdminBundle\Field\Configurator\MoneyConfigurator::getCurrency method.

In my particular case, I have a controller where I render an association field as an embedded form on the create and update pages. This association includes a money field configured as follows:

yield MoneyField::new('targetAmount')
    ->setCurrencyPropertyPath('relation.currency');

However, when the MoneyConfigurator is executed, the field value is null, causing the configuration process to stop at this point:

if (null === $field->getValue()) {
    return;
}

By implementing the suggested changes, it will be possible to improve the field configuration.
