Feat: @inquirer/search - add navigation `instructions` to option

Has hardcoded navigation texts.

Would be nice, if it would match select's {instructions: {navigation: string, pager: string}} to be able to overwrite,
(For translation as well as just plain modification).

Ah yes, this needs to be added. It's already present in the select prompt and both prompts should be consistent. PR welcomed!
