Bug - Wizard - props not being spread in various child components

[nicolethoen]

There are a few things missing from the the props in various Wizard child components

For example in WizardNavItem:

1. The props are not getting spread to the WizardNavItem's li element.
2. The props also don't extend React.HTMLProps<HTMLLIElement>
3. the className is not included in the props, so I cannot add any custom classes to the li element.

These issues are also present in at least:

• WizardNav
• WizardBody
• WizardFooter
• WizardHeader
• WizardToggle

This is inhibiting QuickStart's ability to style individual WizardNavItems to have success/failure/etc styles as part of patternfly/patternfly-quickstarts#299
