message: docs: Fix multiSelectionManager import in Collections example
  Updates the `multiSelectionManager` import in the Collection MultiSelection example to import from `@workday/canvas-kit-react/collection` rather than `../../lib/useSelectionListModel`. This keeps the example self-contained. This will allow the example to be copy-and-pasteable and prevent issues with consumers of the `canvas-kit-docs` package such as the Canvas Site.
