NextJS docs

[KacperMadej]

A simple, full example that works well with NextJS (with loading extra modules, and the full component code) is not documented for v3 nor for v4.
Or at very least the docs are not easy to find.

Resolving this issue could also close:

• TypeError: Cannot read properties of undefined (reading 'AST') #513
• Highcharts v12 with NextJS #502

and/or potentially more.
