Subject: [PATCH] fix: correct instructions in Rust readme for building docker
 image (#5064)

### Description

Fix incorrect instructions in Rust readme for building the docker image.
The build does not work as the readme dictates. Being in the rust folder
gives a `ERROR: failed to solve: failed to compute cache key: failed to
calculate checksum of ref
y1ezs2da6re8bcvxgo9psu1xk::hydxdsbeaxqx3rvjjzako1134:
"/rust/main/config": not found` error. Being at the top level causes a
successful build.

Also have to edit the build script to target the correct directory
dockerfile.
