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.
