feat: Rename --temp-directory option to --temp-dir (#897)

* Rename --temp-directory option to --temp-dir
* Add -t alias

Deprecates the option name --temp-directory in favour of --temp-dir
--temp-directory has been demoted to a yargs alias of --temp-dir
This change makes the option naming consistent using the form --*-dir
