Upgrade instructions

There is a new naming scheme for release artifacts - nwaku-${ARCHITECTURE}-${OS}-${VERSION}.tar.gz. If you use any automation to download latest release, you may need to update it.

The --topics config option has been deprecated to unify the configuration style. It is still available in this release but will be removed in the next one. The new option --topic is introduced, which can be used repeatedly to achieve the same behavior.
