Fix https://github.com/galaxyproject/galaxy/issues/12412 . We have a dependency on `Tempita` (through `sqlalchemy-migrate`), which is abandonware and uses the `use_2to3=True` option of `setup()` in its `setup.py` . The new Setuptools v58.0.0 removed support for 2to3 during builds: https://github.com/pypa/setuptools/blob/main/CHANGES.rst#v5800 As a result Tempita is installed at even older version and importing it raises a SyntaxError. For Galaxy as a full application this has been solved by creating a wheel on https://wheels.galaxyproject.org . But the `galaxy-data` package (which also depends on `sqlalchemy-migrate`) cannot automatically install the tempita-0.5.2 wheel from our alternative package index when installed via `pip install galaxy-data` as there is no syntax to specify that. I've therefore resurrected Tempita from the Bitbucket Mercurial repo (thanks to Software Heritage backups! https://bitbucket-archive.softwareheritage.org/projects/ia/ianb/tempita.html ), converted to a GitHub repo and updated its code to Python 3.6 with 2to3 and pyupgrade.
