shared docs files unclear

There is a difference in file list of `exercises/shared/.docs` files between [Shared Files](https://github.com/exercism/docs/blob/main/anatomy/tracks/shared-files.md#track-specific-files) (debug.md, help.md, tests.md) and [Track Anatomy Example](https://github.com/exercism/docs/tree/main/anatomy/tracks#example) (debug.md, cli.md).
