Doesn't look like passing just a number works anymore, at least based on the basic Wizard example. We should probably update the height prop type to just a string, and update any instance of it being used to pass a string/CSS unit value.

The Wizard height doesn't seem to be adjustable inside a modal still, either. @mcoker should React set the --#{$modal-box}--c-wizard--FlexBasis token as well?

I can update the prop type to string (or fix it so numbers work).

The core counterpart to this isn't merged yet, so it's not setting the flex-basis with the value atm.

Pending further updates to patternfly/patternfly#6457, this PR will need to updated to use the new --#{$wizard}--height token once core is updated in react. Update: token will be the same but this PR will still need the core bump first.

Other than updating/fixing the width prop type so numbers don't break, lgtm! Agree it should be good once this is updated with the latest core.
