55ee3e0f2c feat(ui-patterns): add CollapsibleCardSection component (#46250)
## What kind of change does this PR introduce?

New shared component + docs.

## What is the current behavior?

`AdvancedConfiguration` and `InternalOnlyConfiguration` in the New
Project form each contain bespoke `<Collapsible>` markup. There's no
reusable collapsible section component available to other card/panel
forms.

## What is the new behavior?

- Extracts a shared `CollapsibleCardSection` into
`packages/ui-patterns`, exported via
`ui-patterns/CollapsibleCardSection`
- Refactors `AdvancedConfiguration` and `InternalOnlyConfiguration` to
use it
- Adds design system docs with a live demo at
`/docs/fragments/collapsible-card-section`

This is a prereq for #45707 and #46187, which both consume this
component.

## To test

- [ ] Check that [the Design System
page](https://design-system-git-dnywh-collapsible-card-section-supabase.vercel.app/design-system/docs/fragments/collapsible-card-section)
makes sense
- [ ] Check that the [new project
form](https://studio-staging-git-dnywh-collapsible-card-section-supabase.vercel.app/dashboard/new/)
collapsible sections work as expected

Supabase UI Patterns

This package should be used for components which are built using NPM libraries (react-markdown, reactflow for example), which make no sense to be included in all apps. It should also be used for components which are constructed using various components from the ui package.

This package does not have a barrel file - each component has to be imported from its index (ui-patterns/PrivacySettings, for example). This is intentional so that adding a new component which is used only in 1 or 2 apps doesn't burden the rest of the apps.
