Implement `RepositoryFactorySupport.getEntityInformation(RepositoryMetadata)` instead of `private` overload.

Overriding the proper variant of EntityInformation is now possible because we no longer utilize a private method in addition to the public one leading to partial customization of EntityInformation.

Closes #2053
