update stack.yaml to nightly-2024-07-29 and remove stack-lts-18.13.yaml

Primarily because Windows needs a dependency bump to get stm-2.5.1
for Servant build flag.

This includes Win32-2.13.4.0 and aws-0.24 which adds some features
that windows had been missing out on as well.

Lots of warnings about head and tail will need to eventually be
addressed. Of course AFAIK the uses of it in git-annex are all safe.
