Set up config for Wallaby elections

Set a combined PTL and TC election timeline which starts nominations
a week from now and concludes polling early on Victoria release
week. This reflects the continued shift in shrinking TC size with
four open seats for the coming election. It also presumes the
accompanying governance repository tag will be 0.8.0, the next
available minor version.
