Standardizes the naming scheme for the hh deploy artifacts.
The goerli artifacts had their names migrated to the new style
where proxy is used as a suffix. This is a forwards compatible
change because the tooling will look between both the `contracts`
package and the `contracts-bedrock` package for the artifacts,
meaning that a lookup for the old name and the new name will work.
This will prevent there from being 2 artifacts with the same name
which may break some of the golang hh tooling.
