Summary

Following PRs like #12065, this PR aims to modify existing generate_source_tarball.sh scripts for helm to use the same parameters and behavior as other go vendored packages. So it adds new parameter to the script and modifies the vendored file name to match the naming scheme.

Change Log

• Adds vendorVersion parameter to helm make the scripts use it for naming to add v1 versioning for vendored files
• Renames vendored files for helm to use govendor-v1 naming in it

Does this affect the toolchain?

NO
