Feat: Add Grandine-in-Nethermind support

Analogous to Caplin

" we have Grandine integrated into Nethermind. This allows to achieve the top performance because there is no overhead of Engine API HTTP communication. It’s basically Nethermind binary with embedded Grandine. https://hub.docker.com/repository/docker/sirsedev/test-repo/tags/unstable-542a084-nethermind-1.35.2/sha256:77fcbf04829cf9935a0d3a021cc9266d42c56d3e8f1965d0df44656a31fdbb15 "

Just wanted to note that in this setup Nethermind's and Grandine's data dirs stay separate (the same way as Grandine would not be embedded into Nethermind). So it should be very easy to keep the data directories structure in eth-docker in the way that allows users to switch between separate Grandine/Nethermind and embeded Grandine into Nethermind without resync.

CI for that integration: https://github.com/grandinetech/grandine/pull/476/files#diff-87db21a973eed4fef5f32b267aa60fcee5cbdf03c67fafdc2a9b553bb0b15f34
