remove: remove smeankbn2 from namespace

This commit removes the `smeankbn2` symbol from the `@stdlib/stats/base` namespace due to a package migration.

BREAKING CHANGE: remove `smeankbn2`

To migrate, users should access the same symbol via the `@stdlib/stats/strided` namespace.

Ref: stdlib-js#4797
