You do not need double quote. A 'when' condition does not need to be quoted.
That said a 'when' condition also does not do an effective "grep" to see if
one string is contained in a list of strings. It will do exact matches only.
This will work.

Below I misspell 'RUNING' on purpose to show it works as expected.

Note below that the set_fact is skipped with each iteration of the loop
because 'RUNING' is not found by the regex_search. When a regex_search does
not find what it is looking for it returns the empty string which gets
evaluated to false. Any non-empty string will evaluate to true.
