Fix client kill enums

[watersRand]

This pull request resolves the issue where certain command parameter enums, specifically ClientKillFilters for the CLIENT KILL command, were not publicly exported by the @redis/client package. The purpose of this change is to make the ClientKillFilters enum accessible to all package consumers, eliminating the need for users to rely on an unstable internal import path.

This matters because it provides a reliable and supported way for developers to use commands that require these enums, improving the package's usability and API stability.

Closes #2805

Hi @watersRand, sorry for the late response and thanks for the contribution! This looks good, but we can do a little better here by exporting those to the top level so users can import { CLIENT_KILL_FILTERS } from 'redis'. I made a PR to your branch, so you can just take the changes and we can progress from there
