[3.9] bpo-39039: tarfile raises descriptive exception from zlib.error (GH-27766) (GH-28614)

* during tarfile parsing, a zlib error indicates invalid data
* tarfile.open now raises a descriptive exception from the zlib error
* this makes it clear to the user that they may be trying to open a
  corrupted tar file.
