Fix 23034 - child constructor no longer has invalid access to parent field

[hugin78]

fixes #23034

Problem:
When using extensions with allOff and having a readonly field in the parent, then the generated child class, does not compile, as it access the private field in the parent class directly.

Solution:
This has been solved the same way as in the 'resteasy' library where the access type of the field in the parent is changed from 'private' to 'protected'.

Test:
A unittest has been added to verify the fix.

Summary by cubic

Fixes a compile error in the MicroProfile generator when a child model extends a parent with a readOnly field. Parent fields are now generated as protected so child classes compile correctly.

• Bug Fixes
  • Fixed the unit test to assert Parent.java uses a protected parentField and ensured the test spec (issue_23034.yaml) includes the classType discriminator to reproduce the inheritance case.

^{Written for commit eb40215. Summary will update on new commits.}
