DateTime filter has widget type choices by default

[zorn-v]

Describe the bug
It is assumed that date time filter has single_text widget by default

EasyAdminBundle/src/Form/Filter/Type/DateTimeFilterType.php

Line 78 in 276de1e

'widget' => 'single_text',

But actually is resets to choices somehow.

To Reproduce
Create entity with datetime field for example created_at and add filter to it like

public function configureFilters(Filters $filters): Filters
{
    return $filters->add('created_at');
}

(OPTIONAL) Additional context
Probably some bug when set nested options - in configurator there is set value_type_options.input
