Add java.sql.Timestamp to allowed list to invoke methods similar to java.util.Date

[oleksiimiroshnyk]

• Version of Thymeleaf (and any involved extensions) you are using.
  3.1.1

• Environment: versions of Spring, Spring Boot, or any other
  relevant libraries.

spring boot 3.0.6
hibernate 6.2.6

• Detailed steps to reproduce your issue.

So I have hibernate entity that has a date(java.util.Date) field
protected Date submitDate;

which in runtime seems to become java.sql.Timestamp(it extends java.util.Date)

and in my template I have
${order.submitDate.compareTo(someAnotherDate)>0}

And I got exception, calling method compareTo is forbidden for type class java.sql.Timestamp

While my tests are passing, but in my test I mock DB/hibernate layer and so my entity has java.util.Date not Timestamp.
So I think java.sql.Timestamp should be also added to allowed list
