feat(@dpc-sdp/ripple-ui-forms): update how active step is determined

[lambry]

Issue: https://digital-vic.atlassian.net/browse/SD-1587

What I did

• Update active step and step number logic
• Auto run the main step change validation, just so anyone using a custom beforeStepChange function doesn't need to know how, or remeber to run it themselves
• Add option to exclude steps from review
• Adding more component tests

How to test

• https://app.pr-1346.vic-gov-au.sdp4.sdp.vic.gov.au/test-wfh

Checklist

For all PR's

• I've added relevant changes to the project Readme if needed
• I've updated the documentation site as needed
• I have added tests to cover my changes (if not applicable, please state why in a comment)

For new UI components only

• I have added a storybook story covering all variants
• I have checked a11y tab in storybook passes
• I have added cypress component tests (if the component is interactive)
• Any events are emitted on the event bus using emitRplEvent

Hey @dylankelly, this (1253ce7) "fixed" the typecript errors around the ripple-core-ui imports in ripple-ui-forms, I feel like there must be a better way to achieve this. What are your thoughts?
