[Rust] idl_gen_rust.cpp: (Option/required-aware codegen for unions) (#5850)

* idl_gen_rust.cpp: Fix google/flatbuffers#5849 (Option/required-aware
codegen for unions)

The generated code was assuming that an Option is always returned by the
union-getter method: however, this is only true if the field is not
marked as `(required)`.

* idl_gen_rust.cpp: flip conditional

* idl_gen_rust.cpp: Add comment, as requested in review

The code added is not covered by the integration test
