This PR improves the completions for arguments in the `/docs` slash command. We achieved this by extending the `complete_argument` method on the `SlashCommand` trait to return a `Vec<ArgumentCompletion>` instead of a `Vec<String>`. In addition to the completion `label`, `ArgumentCompletion` has two new fields that are can be used to customize the completion behavior: - `new_text`: The actual text that will be inserted when the completion is accepted, which may be different from what is shown by the completion label. - `run_command`: Whether the command is run when the completion is accepted. This can be set to `false` to allow accepting a completion without running the command. Release Notes: - N/A --------- Co-authored-by: Antonio <antonio@zed.dev>
