How to get to this dat/time stamp on a GitHub repo

HI, trying to template to the date of release on a latest_release_tag url of a GitHub sensor, I dont know how to do this, so seek help in the community:

say I have this repo release tag:

inspecting:

show this to be the goal to find:


my goal is to add this date timestamp to all GitHub sensors, which I now have listed with this:

  - type: custom:auto-entities
    card:
      type: entities
#      title: Github repos
      show_header_toggle: false
      header:
        type: picture
        image: /local/images/github_owler.png
    entities:
      - entity: automation.github_repo_update
        secondary_info: last-triggered
    filter:
      include:
        - entity_id: sensor.github*
          options:
            type: custom:template-entity-row
            state: >
              {% if state_attr(config.entity,'latest_release_url') %}
              {{ state_attr(config.entity,'latest_release_url').split('tag/')[1]}}
              {% else %} {{state_attr(config.entity,'latest_commit_sha')[0:7]}}
              {% endif %}
            secondary: >
fake-->       {{timestamp}} {{ state_attr(config.entity,'latest_commit_message')}}

so need to create sensors (scrape maybe?) for each sensor.github_repo…
Anyone know how to do this please? thanks for having a look!
