[release-automation] Step to build update version binary into zip and store as artifact

[khluu]

• This is to use for automation from product repo
• Builds update_version binary into a python zip file and upload it as an artifact in release-automation pipeline
• Have root_dir as an arg for update_version since automation is using this on a cloned Ray repo
