Improve generated Java examples (#8012)

* Add basic types imports to generated examples

This adds an extension to include basic types imports to generated Java
examples.

* Make some fixes to example generation

* Generate OffsetDatetime correctly

* Create a useful sample for enums, regenerate samples

* Fix BigDecimal as well
