Do not use explicit dependencies on Dockerfile

[spalladino]

We currently need to declare all package dependencies, including transitive ones, to the Dockerfile for each package for CI build:

https://github.com/AztecProtocol/aztec3-packages/blob/3e737216717f05c44d99a2aedc356257f9c3e15f/yarn-project/archiver/Dockerfile#L5-L11

This is error prone, and leads to frequent issues with the CI.

We should instead either:

• Copy the entire project to the dockerfile (ie COPY . .)
• Or have a yarn prepare step at the project root update them

I favor the first one for simplicity. We can move into the 2nd one if performance becomes an issue.
