python3Packages.tensorflow-probability: 0.8 -> 0.15.0

tensorflow-probability 0.8 was broken and marked as such (in #108977)
because of a dependency on dm-tree, which seems not to have been
available.
Since dm-tree is now available in nixpkgs (#152971),
tensorflow-probability is easy to fix and to upgrade.
