How to set version similar to Fedora kinoite?

General
1

I have set up up a github action from ublue template. But the output of the version is main.
I want to have similar version as fedora atomic.

rpm-ostree status
State: idle
AutomaticUpdates: stage; rpm-ostreed-automatic.timer: last run 9h ago
Deployments:
● ostree-image-signed:docker://ghcr.io/tazihad/kandari-nvidia:latest
                   Digest: sha256:5d02568e8190bf61ba42991495a88b7478dc8640f29bb9aa27cdba9b2e4b5384
                  Version: main (2024-07-06T23:06:19Z)

If I make a blue-build from here.
I get similar version as Fedora atomic.

  ostree-unverified-registry:ghcr.io/tazihad/template:latest
                   Digest: sha256:c3ba1872ac20c41f447e3ce7962ec311619828a1748a1113a528e2ac0cc1b52b
                  Version: 40.20240706.0 (2024-07-06T11:26:01Z)

How do I achieve this?
This is my build .yml
