Not sure if you'd be up for reviewing this please @mikeathan-nhs?

I could do with adding some extra bits to the migration guide but the component changes are ready to review

Pushed some extra commits after testing with React Server Components (RSC)

Due to 'use client'; with (partially) server-rendered children, these card child lookups were undefined:

const headingItem = items.find((child) => childIsOfComponentType(child, CardHeading));
const actionItems = items.filter((child) => childIsOfComponentType(child, CardAction));

To fix this, I've made sure card components can be fully server-rendered.

We also had an issue with beforeInput and afterInput` being render functions not JSX.

See the following new commits:

• Add support for visuallyHiddenText to render React elements (more)
• Update FormGroup component to support multiple children
• Prevent text input beforeInput and afterInput from overriding pre…
• Fix "Error: Functions cannot be passed directly to Client Components…"
• Remove unnecessary context from card component
