ci: delete dead step (#9088)

Generating the allocs no longer relies on `geth` so we do not need to
install `geth` as part of bringing up the devnet. We also generate the
allocs once and then persist them to the CI workspace. This will save
~1-1.5 minutes per CI run by no longer installing `geth` as part of
the devnet.
