chore: Update cluster-key-slot to latest

[bag-man]

When using ioredis, with the licence-compliance package, it fails due to a sub-dependency having an invalid licence string. The sub-dependency has fixed that, but ioredis hasn't updated to use it yet, resulting in this output:

ioredis (main) λ  npx license-compliance --allow "ISC;MIT;BSD-3-Clause;BSD-2-Clause;Apache-2.0;Python-2.0;MPL-2.0;LGPL-2.0;LGPL-3.0;LGPL-2.1;0BSD;Unlicense" --report detailed

Upgrading cluster-key-slot, to the latest version, so that this PR that fixes the incorrect licence string is included.

Looks like the tests fail.
