[exporter/debug] change default verbosity from normal to basic (#…

…8846)

This change has currently no effect, as `basic` and `normal` verbosity
share the same behavior. This might change in the future though, with
the `normal` verbosity being more verbose than it currently is (see
#7806).
This is why we are changing the default to `basic`, which is expected to
stay at the current level of verbosity (one line per batch).
