buildmaster: fix Twisted dependency hell by using twisted==22.10.0

Force twisted==22.10.0 which fixes following buildbot master startup
issue:

Unhandled error in Deferred:

    raise PluginDBError('Requirements are not satisfied '
buildbot.errors.PluginDBError: Requirements are not satisfied for buildbot.www:base:
The 'zope-interface>=5' distribution was not found and is required by Twisted

This commit should be reverted once we bump to buildbot >= 3.10 which
has this workaround integrated.
