feat(comp): Add descriptions for release name comp

Ref: HIP 0008

When completing a release name, extra information will be shown for
shells that support completions (fish, zsh).  For example, if I have
two releases: "nginx" and "nginx2", completion would yield:

$ helm history n<TAB>
nginx   -- nginx-6.0.2 -> deployed
nginx2  -- nginx-ingress-1.41.2 -> deployed
