rARCc01198d55f6d: Correct PHPDoc @return value of methods that can return null

Summary

Make the PHPDoc @return say so when the method can also return null instead of an, array, string, or int.
(In case of getCommandHelp(), return an empty string as child implementations do return strings.)

Test Plan

Read the code; run static code analysis.

src/workflow/ArcanistWorkflow.php
293 ↗	(On Diff #2424)	I agree but probably we should update also something else, like this check that originally was a "not empty, not null, not objects without a toString()" check and instead now it's just "not null": https://we.phorge.it/source/arcanist/browse/master/src/workflow/ArcanistWorkflow.php;995072b31fff5c7d77bcb353d25df819bfd3798a$157 (that line was changed during b50a646a3f49) The question may be: is there any Workflow out of there without an help command? If the answer is "maybe yes" let's update `ArcanistWorkflow.php` and adopt: `phutil_nonempty_stringlike()` - if an help may return an object with __toString() (that renders text?) `phutil_nonempty_string()` - if we are sure that it only returns null + string
