When building directly from the repo (either from a git clone or a
download of the zip of the repository) the version reported is very
misleading because it will not have a version label, suggesting it is
actually a 'release' version when in fact it could be anything.
The ./.ci/calculate-version.sh logic is already setup to delete an
existing ./internal/version.txt during a detected release build, so we
can just place one in the repositroy and it won't impact the versioning
of CI and release builds, but will show up when building locally.
