generate-iso is failing - unknown flag --format

[git-Contributor]

I have issue generating ISO on my host machine (Manjaro) using bluebuild cli (same issue with 0.9.3 and 0.9.6).
When using bluebuild from VM via custom blue build image, it works as expected (so the recipe is ok).

Not sure if it is issue with bluebuild cli or docker one.

The error (-vv output.log:

Ok, looks like the error is around docker buildx. I'll have to add an extra check to make sure that is available before trying to run builds with docker.

I released 0.9.7 with a fix for this. Let me know if this is fixed for you

Tested with version 0.9.8. It fixed it...it now stops right at the start with the info that I am missing buildx :) my bad, did not realized/know I need that. After installing buildx with docker it works flawlessly. Thanks!
