* Fix used VAR

* Improve doc

* ci: Update .build-push-image jobs to use the new build-injected.sh

* ci: fix path to build-injected.sh script

* Rename the release artifacts folder to prevent confusion due to a similar folder in the gitlab CI

* ci: check out polkadot repo in .build-push-image

This seems far cleaner than copying the entire scripts/ folder into our
job artifacts.

* feat(build-injected.sh): make PROJECT_ROOT configurable

This lets us avoid a dependency on git in our CI image.

* ci: build injected images with buildah

* ci: pass full image names to zombienet

* Add missing ignore
