Integrate gitlab-ci/PBB-32-flash-n-go-deploy-folder-no-suffix

Commit: seco-ne/yocto/infrastructure/gitlab-ci@7bd78810

PBB-32 Fix suffix addition in FNGo pipeline for custom projects due to an issue in GitLab where escaped variables are not correctly passed to child pipelines, a workaround is required. As a result, we use raw variables. The DEFERRED_RELEASE_VERSION variable was introduced for this purpose. However, for custom builds, we have an additional place where we modify the DEFERRED_RELEASE_VERSION variable to add a suffix. Therefore, extra interim variables need to be added to handle the workaround and ensure we get the raw variable in the end.
