fix(fish-completions): don't execute with env

Amolith · Amolith · commit de05740bbf5f · 2025-12-04T11:57:37.000-07:00
Using `env` broke Fish completions because `command` is a Fish builtin
while `env` is an external program unaware of what Fish does and doesn't
provide:

    env: ‘command’: No such file or directory

Fish supports `FIELD=val` natively, so we can just remove `env`.
