`devShell` `ghci` may not work with GHC 9.8

[peterbecich]

Using this example https://github.com/peterbecich/ghcid-issue, which has

          basePackages = pkgs.haskell.packages.ghc98;

, loading ghci in the devShell results in:

$ ghci 
Loaded package environment from /home/peterbecich/.ghc/x86_64-linux-9.8.2/environments/default
GHCi, version 9.8.2: https://www.haskell.org/ghc/  :? for help
<command line>: cannot satisfy -package-id base-4.19.1.0-eafb
    (use -v for more information)

ghci in the devShell works fine with the default GHC 9.6.

ghci also works fine outside of the devShell using GHCup-provided GHC 9.8 and ghci.
