Auto merge of #12244 - rev112:package-repro-pure, r=aneeshusa

Create .tar.gz package deterministically using Python's "tarfile"

<!-- Please describe your changes on the following line: -->
A development of #12108, creates a .tar.gz package using the `tarfile` and `gzip` modules, without external dependencies. Fixes #11981.
Also this fixes the issue when the existing `resources/` directory didn't allow to create a new package and failed with "File exists" error.
