As commented by @glyph

Since we've added the buildbot link to trac pages, force-builds.py is
basically obsolete.  I think we should  just scrub all mentions of it,
and probably delete it.

I have created a ticket to remove it and clean documentation:

https://github.com/twisted/twisted-dev-tools/issues/5

Is there anyone else still using this tool?
Should we keep it and rather than removing it, improve its documentation?

Thanks!
