Update conda recipes pinning of repo dependencies (#3666)

Ensure all conda packages created in this repo that depend on other packages are all version pinned to the same build number. This way it prevents a conda solve from picking mismatched versions of `cuml` and `libcuml` that can break this repo during builds and testing.
