starship: fix type of settings to allow all valid value

Previously, type check of `programs.starship.settings` fails for some
valid settings, such as `c.commands = [["cc" "--version"]]`.

The commit fix the `type` argument passed to `mkOption`, so
`programs.starship.settings` can accept all valid values (of toml
type).
