      title: '[Automation] Bump Golang version to {{ source "latestGoVersion" }}'
      description: |
        It requires the version to be bumped first in golang-crossbuild project, then a new release will be added to:
        https://github.com/elastic/golang-crossbuild/releases/tag/v{{ source "latestGoVersion" }}.
        Otherwise it will fail until the docker images are available.
