stack.yaml: Update to lts-19.33 and aws-0.24

This enables some new features that need the new aws.

Win32 downgraded from the version in lts-19.33 because git-annex does not build
with that version, and newer versions of Win32 need a newer filepath version,
which can't be upgraded while using lts-19.33.
