Add branch metadata to conda dist archives.
This MR proposes adding branch metadata to conda-dist archives.
When publish_conda_env
is triggered from a working branch, the branch name is appended after the version number.
See e.g . https://gitlab.wikimedia.org/repos/generated-data-platform/differential-privacy/-/packages/191
When publish_conda_env
is triggered from a RELEASE branch, no metadata is added to the archive file name.
