scripted-diff: test: remove 'descriptors=True' argument for createwallet calls

Descriptor wallets are already created by default since v23.0, but
since the recent legacy wallet removal this parameter *must* be True
(see commit 9f04e02ffa), i.e. still
passing it wouldn't contain any information for test readers
anymore. So simply drop them in the functional tests in order to
reduce code bloat.
