actions: change trigger phrase for kata-deploy action

Let's change the kata-deploy github action trigger from:
  '/test kata-deploy'
to
 '/test-kata-deploy'

which will hopefully reduce the number of false triggers caused when
we issue the 'normal' CI runs that are triggered by other
'/test xxxx' phrases.

Fixes: #971
