Replace deprecated PropertyFetchToMethodCallRector with custom rule

PropertyFetchToMethodCallRector was deprecated in Rector 2.2.6 as it
was considered too generic. This commit introduces a custom
FakerPropertyToMethodCallRector that specifically handles the
transformation of Faker\Generator property access to method calls.
