### Minimal code example

```dart
const SizedBox(width: 8.0),
Flexible(
child: FormBuilderDateTimePicker(
inputType: InputType.time,
style: Theme.of(context).textTheme.bodySmall,
name: 'pt_PT',
decoration: textFormFieldDecoration(
context, 'Test pt_PT'),
initialDate: DateTime.now(),
initialTime: TimeOfDay.now(),
),
),

const SizedBox(width: 8.0),
Flexible(
child: FormBuilderDateTimePicker(
format: DateFormat('HH:mm'),
inputType: InputType.time,
style: Theme.of(context).textTheme.bodySmall,
name: 'en_UK',
decoration: textFormFieldDecoration(
context, 'Test en_UK'),
initialDate: DateTime.now(),
initialTime: TimeOfDay.now(),
onChanged: (value) {},
locale: Locale('en', 'UK'),
),
),
```

### Current Behavior

When switching to input text mode to enter time manually, it won't let me put a time above 12hrs.

Furthermore, there is no AM/PM selector in certain locations, such as in my case Locale('pt', 'PT'), but if I change the Locale of FormBuilderDateTimePicker to Locale('en', 'UK') An option will appear to choose AM/PM

### Expected Behavior

I want to use AM/PM selector outside Locale('en', 'UK')

### Steps To Reproduce

Testing Code:

```dart
const SizedBox(width: 8.0),
Flexible(
child: FormBuilderDateTimePicker(
inputType: InputType.time,
style: Theme.of(context).textTheme.bodySmall,
name: 'pt_PT',
decoration: textFormFieldDecoration(
context, 'Test pt_PT'),
initialDate: DateTime.now(),
initialTime: TimeOfDay.now(),
),
),

const SizedBox(width: 8.0),
Flexible(
child: FormBuilderDateTimePicker(
format: DateFormat('HH:mm'),
inputType: InputType.time,
style: Theme.of(context).textTheme.bodySmall,
name: 'en_UK',
decoration: textFormFieldDecoration(
context, 'Test en_UK'),
initialDate: DateTime.now(),
initialTime: TimeOfDay.now(),
onChanged: (value) {},
locale: Locale('en', 'UK'),
),
),
```
Using my default Location as pt_PT
Introduza uma hora válida = Enter a valid time

Meanwhile specifying locale as us_UK:
It display's the AM/PM selector, so I can use 12Hrs format and select if it AM/PM
