JDK21 toJson failure

# Gson version

version 2.10.1
Using JDK 21 to perform fromJson, the Date type contains hidden characters causing the failure of the toJson operation.

In GitHub issues, it seems that I cannot illustrate it, so I will use images to show

```
public static void main(String[] args) {
String jdk17="{\"clientId\":\"123\",\"secret\":\"123\",\"creator\":\"trump\",\"gmtCreated\":\"Dec 14, 2023, 11:07:35 AM\",\"gmtModified\":\"Dec 15, 2023, 4:45:51 PM\"}";
OauthClient oc17 = gson.fromJson(jdk17, OauthClient.class);
String jdk21= "{\"clientId\":\"123\",\"secret\":\"123\",\"creator\":\"trump\",\"gmtCreated\":\"Mar 21, 2022, 11:03:07 AM\",\"gmtModified\":\"Mar 21, 2022, 11:03:07 AM\"}";
OauthClient oc21 = gson.fromJson(jdk21, OauthClient.class);
}
```

```
