Add support for Next JS

[incorbador]

Why

Additionally to @corbado/react that supports only react we want to add a package that supports users that want to include Corbado in their Next JS project. We might break this issue down into smaller tasks as we start working on it.

TODO

• Create a new package: @corbado/next-js
• Check other Next JS packages (e.g. Clerks) to get a good understanding of the challenges
• Add a new example application (next-js-example)
• Complete and test the package(s)

Acceptance criteria

• UI components are configurable similar to @corabdo/react (translations and styles)
• UI components work in our new example

Implementation idea

• tbd. (especially how much we want to optimize for server components here)
• things that should be included: middleware

For now have just built an example on how to use the react package inside a Next application.
