Incorrect values for --timings-type parameter

[ppaulis]

The doc for --timings-type is incorrect. The circleci cli tool gives the following message:

Error: invalid argument "file" for "--timings-type" flag: unknown timings type, allowed values are "filename", "classname", "testname", and "autodetect"

Description

Fixed the list of values for the --timings-type parameter.

Reasons

Because the current list is incomplete and wrong.

Thank you for fixing this for us @ppaulis! 🎉

We also have a reference guide for the environment CLI now so I might consider removing the duplicated tables on this page to avoid more confusion in future: https://circleci.com/docs/guides/toolkit/environment-cli-usage-guide/#run-2
