build with Cabal-3.12 to try to unbreak the cron job

stackage-server-cron: Unable to parse cabal file from package webdriver-precore-0.2.0.1@sha256:2c644f12cb915bd6491da97af448bb74270cdcee8260f4a39f11c7594b6153c4,7407 (from Hackage)
- 0:0: Unsupported cabal-version 3.12. See https://github.com/haskell/cabal/issues/4899.  <= error from Cabal
The cabal file uses the cabal specification version 3.12, but we only support up to version 3.8.
Recommended action: upgrade your build tool (e.g., `stack upgrade`).
