Good catch @DeimerM. I’m aligned with this change, and I don’t think the added build time (under 2 minutes) is a major concern
It would be nice to expose this as a configurable flag, maybe we can leave the default to true (enable disk space cleanup), while allowing it to be disabled for environments where it’s not required (e.g., larger runners) to reduce build time
Please let's make sure this option is documented in the README

@DeimerM just a small suggestion

| - If this field is set to ``true``, some non-essential pre-installed resources on the runner will be removed to free up disk space and avoid running out of resources during image builds. Default is ``true``. Recommended when using GitHub’s default hosted runners or any runner with limited resources. |

Description
This PR adds a specialized cleanup step to the image build pipeline. It is designed to remove default resources and pre-installed software provided by the GitHub Actions (GA) runners that are not necessary for our specific build process.
Why is this necessary?
We have encountered no space left on device errors (specifically during the #111 importing to docker stage) because the standard GitHub-hosted runners have a limited disk capacity (approx. 14GB–18GB). Large Docker builds—especially those involving heavy node_modules or multiple layers—can exceed this limit.
By clearing out unused tools like the Android SDK, .NET, and the hosted tool cache, we can reclaim up to 20GB+ of additional disk space for the build process.
