https://bitbucket.org/jython/jython no longer mirroring (BB-11140)

An hg mirror of the Jython project was setup a few years ago at:

https://bitbucket.org/jython/jython

It hasn't synced in a couple of months. It should be a mirror of:

http://hg.python.org/jython

Could we fix it back to mirroring? Assigning to Brodie because IIRC you originally set this up. Thanks!
