## What
This adds a workflow which automatically triggers on published releases
to update the version number for our version checker. In addition it
adds a workflow dispatch, in case the version number ended up wrong
after an automatic run (for instance when patching an earlier released
minor).
## Observations
Currently the version checker which receives the update only validates
that the new version is also valid semver, it does not however
check/verify that we're not suddenly telling it an older version is the
newest (improvement available in the version updater repo).
