Fieldgenerator should not accept private getter

[julgus]

Describe the bug
Under certain conditions, the fieldgenerator accepts private getters and generates code that won't compile.

Expected behavior
If the getter is private the fieldgenerator should issue a warning at runtime and generate a reference getter that throws an exception.

The field films has a private getter:

    @Getter(value = AccessLevel.PRIVATE)
    @ManyToMany(mappedBy = "actors")
    private List<Film> films = new ArrayList<>();

Should generate (whether this is an optimal solution is up for discussion but this is the way it is designed to work at this point) :

    /**
     * This Field corresponds to the {@link Actor} field "films".
     */
    public static final ReferenceField<Actor, List<Film>> films = ReferenceField.create(
        Actor.class,
        "films",
        actor -> {throw new IllegalJavaBeanException(Actor.class, "films");},
        false
    );

Actual behavior
The generated ReferenceField references Actor::getFilms which is unavailable to the compiler of that class:

    /**
     * This Field corresponds to the {@link Actor} field "films".
     */
    public static final ReferenceField<Actor, List<Film>> films = ReferenceField.create(
        Actor.class,
        "films",
        Actor::getFilms,
        false
    );

How To Reproduce
Build the fieldgenerator-test module with IntelliJ (error does not occur when building with Maven).

Build tool
IntelliJ

JPAStreamer version
3.0.2

JPA Provider
Hibernate 6.0.2.Final

Java Version
11.0.27

I think the difference arises because the accessors Lombok generates are available at build time with IntelliJ and are erroneously detected as standard getters.
