fix: dockerfile multichain

[ppca]

Has been broken since we change folder structure. already tested on develop this works.
This will fix the down dev env.

There were 2 bugs with the Dockerfile.multichain:

1. we copied whole mpc folder instead of chain-signatures/ folder. the issue there is the top level mpc folder has no Cargo.toml file, nothing will be built;
2. after fixing 1), I find that https://github.com/near/mpc/blob/develop/chain-signatures/.cargo/config.toml#L2 actually ask to put the built binary to ../target, instead of target. But later when we do
   COPY --from=builder /usr/src/app/target/release/mpc-recovery-node /usr/local/bin/mpc-recovery-node
   it is copying from target instead of ../target. Which will copy nothing

This can be verified by built artifact size. If you look at artifacts size: correct ones are 60+mb, incorrect ones are only 50+ mb. I think reflects the fact that actually nothing is built.

Also included a dependency fix. Because the dmd/bump-dependencies branch has been deleted, I updated to a commit hash that merged.
