[Feature]: Support linting with PyRight

[maxfischer2781]

Describe the feature

Type checking with PyRight should work just as well as MyPy. It is important that the CI also runs PyRight checks, since the type checkers disagree on some of the more involved features (see e.g. #124).

The PyRight docs have a section on CI.
