set version to 2022.09.1

Starting with this release we will no longer use "unknown" as the
default software version string used in cases where the version cannot
be determined from context. Instead we commit the release version string
to git so that any software built from the tagged commit will have the
appropriate release version string. After the release we will commit a
post-release version string as the new default.

We will continue to use the commit hash as version string when the
software is built inside a git repository.
