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

/**
* This file is created to handle our discriminated unions
* validations primarily for union returns from Contentstacks
* GraphQL server.
*
* In the case of a new block being added to the union in Contenstack,
* Zod will throw because that typename is not expected ("invalid_union_discriminator").
* Therefore we add a safety that we return everytime we stumble upon
* the issue and then we filter it out in the transform.
*
* This replaces the `cleanEmptyObjects` function that would require
* everyone to never make a mistake in adding __typename to root
* anywhere (or any other potentially global fields in case the return type
* is an Interface e.g).
