fix flaky test TimeTest.testBetweenWithMask

Sometimes the test failed when
* "moment + 1 second" appeared to be in tomorrow, or
* "moment - 1 second" appeared to be in yesterday

Example of failed build:
https://github.com/datafaker-net/datafaker/actions/runs/23998847901/job/69991488685?pr=1789

```
Expecting actual:
  23:59:22
to be strictly before:
  00:00:00.106916777

	at net.datafaker.providers.base.TimeTest.testBetweenWithMask(TimeTest.java:107)
```
