cabal.project: Bump index states

[erikd]

This is the first step in making this build with ghc-9.8. Only the index-state values were changed.

[lehins]

Whenever index state is updated we also need to update nix flakes

[erikd]

@lehins Updating the CHaP index-state was easy:

nix flake lock --update-input CHaP

However, I tried every combination I could think of for

nix flake lock --update-input hackage.nix

and none of them worked.

@erikd it's written down: https://github.com/input-output-hk/cardano-ledger/blob/master/CONTRIBUTING.md?plain=1#L64

So why is it different between projects? I have touched 10 different input-output-hk projects in the last week. Every project doing it in a unique snowflake way is a HUGE pain in the neck.
