append_simulations method return types for NLE and NRE classes is different from the return type of their parent method

[abelaba]

The append_simulations methods for the NRE and NLE classes have a return type of RatioEstimator and LikelihoodEstimator respectively, but the parent method they inherit has a return type of NeuralInference.

Currently, there is a # type ignore on the method calls so pyright will not display an error. But if you remove those comments pyright will display an error that there is a return type mismatch.
