fix(nervous-system): release runscript doesn't prompt you to update mainnet-canisters.json (dfinity#3792)

The release runscript doesn't need to prompt you to update
mainnet-canisters.json since PRs to do so are created automatically now,
for example in dfinity#3727. We still need to remember to merge the
automatically-created PR, but hopefully that will be pretty easy
