heptapod-ci: make Windows jobs manual again

The dance continues, we make the Windows tests optional once again since we
don't have Windows runners available anymore. We're working on getting new ones
in a more stable fashion, hopefully soon.

Differential Revision: https://phab.mercurial-scm.org/D11957

# Read the output of a "svn log --xml" command on stdin, parse it and
# print a subset of attributes common to all svn versions tested by
# hg.
