spring-projectsGH-9050: JDBC LockRepository: Use Timestamp instead of LocalDateTime

Fixes: spring-projects#9050

Turns out not all JDBC drivers support a `LocalDateTime` type conversion.

* Use `Timestamp.valueOf(LocalDateTime)` for `TIMESTAMP` params of the queries
in the `DefaultLockRepository`

**Auto-cherry-pick to `6.2.x` & `6.1.x`**
