Anton Gunnarsson 80100e7631 Merged in monorepo-step-1 (pull request #1080)
Migrate to a monorepo setup - step 1

* Move web to subfolder /apps/scandic-web

* Yarn + transitive deps

- Move to yarn
- design-system package removed for now since yarn doesn't
support the parameter for token (ie project currently broken)
- Add missing transitive dependencies as Yarn otherwise
prevents these imports
- VS Code doesn't pick up TS path aliases unless you open
/apps/scandic-web instead of root (will be fixed with monorepo)

* Pin framer-motion to temporarily fix typing issue

https://github.com/adobe/react-spectrum/issues/7494

* Pin zod to avoid typ error

There seems to have been a breaking change in the types
returned by zod where error is now returned as undefined
instead of missing in the type. We should just handle this
but to avoid merge conflicts just pin the dependency for
now.

* Pin react-intl version

Pin version of react-intl to avoid tiny type issue where formatMessage
does not accept a generic any more. This will be fixed in a future
commit, but to avoid merge conflicts just pin for now.

* Pin typescript version

Temporarily pin version as newer versions as stricter and results in
a type error. Will be fixed in future commit after merge.

* Setup workspaces

* Add design-system as a monorepo package

* Remove unused env var DESIGN_SYSTEM_ACCESS_TOKEN

* Fix husky for monorepo setup

* Update netlify.toml

* Add lint script to root package.json

* Add stub readme

* Fix react-intl formatMessage types

* Test netlify.toml in root

* Remove root toml

* Update netlify.toml publish path

* Remove package-lock.json

* Update build for branch/preview builds

/**
* AppRouteHandlerFnContext is the context that is passed to the handler as
* the second argument. This is only done for Route handlers (route.js) and
* not for middleware. Middleware`s second argument is `event` of type
* `NextFetchEvent`.
*
* Auth.js uses the same pattern for both Route handlers and Middleware,
* the auth()-wrapper:
*
* auth((req) => { ... })
*
* But there is a difference between middleware and route handlers, route
* handlers get passed a context which middleware do not get (they get a
* NextFetchEvent instead). Using the same function for both works runtime
* because Auth.js handles this properly. But fails in typings as the second
* argument doesn't match for middleware.
*
* We want to avoid using ts-expect-error because that hides other errors
* not related to this typing error and ts-expect-error cannot be scoped either.
*
* So we type assert this export to NextMiddleware. The lesser of all evils.
