Use yaml anchors for workflows (#10574)

cdce8p · web-flow · commit d94ba23e0159 · 2025-09-21T07:08:35.000+02:00
Github added support for YAML anchors in workflow files. They don't support key-merge / overrides but it's at least a start. - https://github.blog/changelog/2025-09-18-actions-yaml-anchors-and-non-public-workflow-templates/ - https://docs.github.com/en/actions/reference/workflows-and-actions/reusing-workflow-configurations#yaml-anchors-and-aliases - Good overview over the yaml anchors syntax: https://support.atlassian.com/bitbucket-cloud/docs/yaml-anchors/
