terminfo had a new release on hackage and we only ship the latest
version currently, so every GHC gets the newest version. Whether this is
correct, is another question, occurs to me – we'll have to look into
whether we should fix this at some point.
GHC HEAD is a pre basically pre GHC 9.8 (or rather 9.7 something).
Let's name the configuration like the upcoming release, so we can use it
immediately when the new release comes out. Instead of keeping the HEAD
configuration like we used to, we'd create a new (empty) one.
