Document Mono Repo Support (for 8.4 doc release) #152
Description
There is now support for pinned-dependencies.
We need to extend the docs in the build configuration and it's probably worth considering an extra page in the Build System category called Monorepo setup.
- add a note that the mono repo support is only supported for 8.4 and above
- add some instructions on how to use pinned dependencies in watch mode
