 Given an object `X` of the category `Top` of topological spaces and a point `x : X`, this file
 builds the type `open_nhds x` of open neighborhoods of `x` in `X` and endows it with the partial
 order given by inclusion and the corresponding category structure (as a full subcategory of the

chore(*): shake imports (#10199)

Remove Data.Set.Basic from scripts/noshake.json.
Remove an exception that was used by examples only, move these examples to a new test file.
Drop an exception for Order.Filter.Basic dependency on Control.Traversable.Instances, as the relevant parts were moved to Order.Filter.ListTraverse.
Run lake exe shake --fix.
