Refresh metadata in sharktank/setup.py. (#247)

* Drop author email for consistency with shortfin (we could also pick a
mailing list or more up to date contact email)
* Update URL following repository rename

More will be needed as we add a dep on `shortfin` and resume regular
publishing of this `sharktank` package to
https://pypi.org/project/sharktank/

sharktank/setup.py
