Increase verbosity of Hypothesis on CI. (#28799)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/28799
When the verbosity is quiet, hypothesis no longer prints the real
error when it finds multiple falsifying examples: it just says
that there are two failures. This is supremely unuseful. Make
it print more.
