Fixing docker files to work with workspace

[danenbm]

Notes

• Cleaned up extraneous copies and added the missing cargo chef cook steps in das_api and nft_ingester. Before it wasn't actually running the cargo chef cook step for those two.
• However, currently cargo chef stuff can build load_generation but not das_api and nft_ingester. See error message below. Its as if its not activating the rpc feature for digital-asset-types:
• For the short term to unblock this work, I commented out the cargo chef cook step for das_api and nft_ingester which makes it equivalent to how it built prior to this PR.

Testing

• This version builds and runs.
• Sent Bubblegum transactions using the transaction forwarder and they properly indexed into the Postgres database.
• Can access the DAS API served on localhost.
