Fix Houdini CI Caching

[Idclip]

# We bumped from the 2021 CI image to 2023 to fix some OpenSSL issues
# with the Houdini download script. In so doing we broke some of the caching
# between this job and the jobs in houdini.yml which _don't_ use the 2023
# image yet. The issue is that the cache action will use zstd if it's
# available to zip the cache and this causes it to be inserted with a unique
# hash which images without zstd (i.e. the 2021/2022 images don't have
# access to). For now, uninstall zstd here instead of installing it
# everywhere and ask the LF to add zstd to the older base images.

This should now pass once in master
