[WizardInline] Convert styled-components to scss (and story)

[kevinsperrine]

We need to remove styles that are done using styled components and remove the package as a dependency. It may make sense to do a local visual snapshot with Cypress before removal to tell if we are introducing any regressions. Concentrate on deprecated components and stories last.

@kevinsperrine This is deprecated component. Do we need to fix it?

[kevinsperrine]

@Ritu-Thakur Yeah, we still want to remove it so that we can remove styled-components from our dependencies. You can leave deprecated components for last in priority.
