[Ada] Fix #7569 by defining x-is-model-type when property is local to…

… the YML file (#7655)

* Ada generator generates "=>" (correct syntax) instead of "->". Fixes #7450

* Updated the Ada petstore samples

* Committing "VERSION" file and the rest of the petstore samples

* Changed default project name and package name for Ada, not to have circular dependencies between gpr files.

* Ada code generator now adds x-is-model-type every time a model is defined locally in the YML file.

Fix #7569.
