🤖 Fix invalid UUIDs (#1112)

* 🤖 Fix UUIDs that had an invalid form

This commit regenerates each UUID that was not a valid version 4 UUID
compliant with RFC 4122 in the canonical textual representation.

Each UUID should match this regular expression:
`^[0-9a-f]{8}-[0-9a-f]{4}-4[0-9a-f]{3}-[89ab][0-9a-f]{3}-[0-9a-f]{12}$`

A track can generate a suitable UUID by running `configlet uuid`.

* 🤖 Fix UUIDs that were shared locally

This commit regenerates each UUID that was shared within the track.

Every UUID should be unique Exercism-wide.

A track can generate a suitable UUID by running `configlet uuid`.

* 🤖 Fix UUIDs that existed on other tracks

This commit regenerates each UUID that also existed elsewhere on
Exercism.

Every UUID should be unique Exercism-wide.

A track can generate a suitable UUID by running `configlet uuid`.
