[AIRFLOW-XXXX] Increease verbosity of static checks in CI (apache#7200)

The latest version of pre-commit supports showing execution times
for particular checks. This was a feature requested in
pre-commit/pre-commit#1144 and they
finally implemented it after long time saying "no" :).

This commit enables it with --verbose flag - which is also useful
as it shows hook ids and some extra information printed by
some plugins.
