FeelEngineClock is not set using the builder

[saig0]

Describe the bug
The FeelEngine can be created by providing a FeelEngineClock. This works when using the constructor but doesn't work when using the builder.

To Reproduce

1. Create the FeelEngine using the builder and provide a clock
2. Set a fixed date on the clock
3. Evaluate the expression now()
4. Verify that the result of the evaluation is not the time that is set in the clock

Expected behavior
The engine uses the clock.

Environment

• FEEL engine version: 1.12.0, 1.12.1
• Affects:
  • Camunda BPM: [7.x]
  • Zeebe broker: 0.25.0 (Support now for date / time / date and time constructors camunda#5140)
