In effort to keep the Examples Directory as easy to navigate as
possible, and to keep the Payload Monorepo only as verbose as it needs
to be, we need to remove all alternatives from the Examples Directory.
This includes setups that interact with Payload from a standalone
server, keeping only the Payload recommended "combined" Next.js +
Payload setups. This will also be applied to all other examples that use
this setup, i.e. draft preview, live preview, etc.
Removes examples that are now duplicative or unnecessary due to new
features in 3.0:
### Custom server
This one can be removed in favor of [Next.js
documentation](https://nextjs.org/docs/pages/building-your-application/configuring/custom-server)
### Hierarchy
The new `join` field can solve for many of the use cases for the
`hierarchy` example. Bi-directional relationships with the `join` field
should be preferred here.
### Nested Docs, Redirects
Our website template showcases how to use the `nested-docs` and
`redirects` plugins in-depth, with real-world examples.
### Virtual Fields
Virtual fields have gotten significantly easier and can now be defined
by specifying `virtual: true`. Not a big need for a full example any
longer.
