Fix bug in search command

The endpoint set for the Pokémon [selection](https://github.com/digitalghost-dev/poke-cli/blob/27ff7c96c4fc3621166756831acce738844291d9/cmd/search/model_input.go#L77) for the `search` command has been accidentally set to `ability` which is not allowing a user to search for a Pokémon since it's using the ability endpoint.
