Adding initialTime parameter to MacosTimePicker

[Abbas1Hussein]

I have added the initialTime parameter to the MacosTimePicker widget, allowing to set an initial time value for the picker.

Minor Change: Added a void return type to OnDateChanged and OnTimeChanged.

The change has been tested to ensure proper functionality.

Checklist

• Incremented the package version in pubspec.yaml (2.0.3).
• Updated the CHANGELOG.md.
• All code is properly formatted and comments are added.
• Verified that there are no Dart analysis warnings.
• Tested and confirmed that the changes work as expected.
