Prune #Bottom states when branching

[goodlyrottenapple]

Fix for change introduced by #3637, wherein branching could contain bottom states which were not being pruned. (see runtimeverification/pyk#634 (comment))

Code change LGTM.
Re-ran the integration test in CI 🤞

Curious, why would you like to remove those dependencies?
Maybe we should adapt the scripts that check or re-freeze if we need to remove them.

I have already removed these from the booster. they should not be fixed because the nix version of cabal comes with a different version of alex and happy and cant figure out a build plan using these

That did not work, though... kore-exec gets killed (error 137) in a search command

krun --haskell-backend-command kore-exec --definition ./test-kompiled --search-final 2.test \
    --output-file 2.test.out --output /tmp/nix-shell.NiDd7o/.krun-2023-09-06-23-59-15-7rLPGoxTwy/result.kore  \
    --searchType FINAL --search

@goodlyrottenapple @geo2a I've also addressed this issue by pruning the #Bottom branches in pyk right now.
