Fix for pre-commit

[ashnair1]

Type ignores added in 135f564 were not reflected in the pre-commit environment since scikit-image was not declared a dependency. This caused the mypy hook to fail with the following message:

pyupgrade................................................................Passed
isort....................................................................Passed
black....................................................................Passed
flake8...................................................................Passed
pydocstyle...............................................................Passed
mypy.....................................................................Failed
- hook id: mypy
- exit code: 1

Can we also add pyvista to solve the vhr10 issue?

[ashnair1]

The issue in vhr10 was due to scikit-image not being in the additional_dependencies section so it's solved now.

Also, pyvista is already in the list.
