[wip] remove deprecation warning

[kbrock]

introduced #19346 fixes:

DEPRECATION WARNING: validate_credentials_task is deprecated and
will be removed from ManageIQ K-release (use verify_credentials_task instead)
(called from block (4 levels) in <top (required)> at
spec/models/mixins/authentication_mixin_spec.rb:293)

If you want it solved a different way, just give the word

The UI still hasn't switched over to using the new method yet so we should probably continue to test the old one for now

[kbrock]

wip until ui is switched

[Fryguy]

Didn't you already try this in #19380 ?

[kbrock]

ugh - I hate deprecation warnings. well this one actually passes the tests. so it is better?

[kbrock]

Everything looks fine. 👍

Until we get the UI off of the old method I think it still has to be tested.
