  Add files to `__init__` for autocomplete in VS Code
  When writing in vs code the autocomplete only works for modules imported in an `__init__.py` file, e.g. `pn.widgets.IntSlider` work but `pn.viewable.Viewer` does not.  See here:

  The solution is pretty easy as `.viewable` only needs to be added to the `__init__`.

  I don't know if #3132 will fix this. When you have time @MarcSkovMadsen can you check this?
