Minimal API Validation should respect [JsonPropertyName]

### Is there an existing issue for this?

### Describe the bug

Related to #61764.

If a parameter bound to a Minimal API endpoint from the request body uses explicit `[JsonPropertyName]` attributes to control serialization, this value is not used to generate responses when validation fails.

https://github.com/dotnet/aspnetcore/blob/89bd3386c750af8331900a26f18ebe54d5b9f2e7/src/Validation/gen/Parsers/ValidationsGenerator.TypesParser.cs#L201-L203

For example a model property such as this:

```csharp
[JsonPropertyName("plaintext")]
[Required]
public string Plaintext { get; set; } = string.Empty;
```

Generates an error such as the below when absent from a request:

```json
{
"title": "One or more validation errors occurred.",
"errors": {
"Plaintext": [
"The Plaintext field is required."
]
}
}
```

It's possible to override the value in the message using `[Display]` (at the cost of additional duplication), but it isn't possible to override the error property name:

```diff
+ [Display(Name = "plaintext")]
[JsonPropertyName("plaintext")]
[Required]
public string Plaintext { get; set; } = string.Empty;
```

### Expected Behavior

The `Name` value of `[JsonPropertyName]` is used as the default for the `Name` and `DisplayName` values if not overridden by `[Display]` (or some other mechanism that should take precedence) to generate a response like the following:

```json
{
"title": "One or more validation errors occurred.",
"errors": {
"plaintext": [
"The plaintext field is required."
]
}
}
```
