Wilma beta

[ripleymj]

Updated beta vars for Wilma, and Packer runs cleanly. A few Ubuntu 24.04 fixes in our course playbooks though:

• The partner (codec) repo appears to have been deprecated for some time and is now finally dead
• The sqlite package for sqlite2 has been dropped in favor of sqlite3
• Ansible/python no longer allows system-wide pip installs, which is what we used for darglint. In Ansible 2.17 you can force install, but we're stuck with 2.16. Also, darglint has been abandoned. There is a darglint2 spiritual successor, but even that maintainer suggests finding something else. I just dropped all of it for now.
• haskell-platform has been dropped, so I reverted to installing ghc directly
