Fix argument deprecation (#404)

* use renamed_arg instead of deprecated_arg_names

* remove python 3.8 from github actions

* use np.array instead of np.matrix when densifying

* test up to python 3.11

* more verbose assertion

* change scanvi score for testing

* change scvi score for testing

* remove integration from code coverage

* less exact test for scvi and scanvi
