docs: update `creating libraries` guide (#43982)
docs: update `creating libraries` guide (#43982)

We update the `creating libraries` guide to remove View Engine references. This is because in version 13 users are no longer able to build libraries using View Engine.

In addition to the above, we also remove references to `npm link`. As this is actually not a recommended workflow, and was mostly needed in older versions of the CLI prior to version 6, were multi-projects workspaces were introduced.

Closes #43949
