Disable queryable built-in feature in docs YAML tests (elastic#124684)

The .security index is created asynchronously on a cluster startup. This
affects some of the docs YAML tests in a way that they need to account
for the existence of the .security index or wait for the index to be
created and green. This PR disables the feature for docs YAML tests.
Disabling the feature in docs YAML tests will solve the flakiness
without affecting the coverage.
