workflow automatically fails because it uses a deprecated version of `actions/upload-artifact: v2

Hey there,

thanks for creating the bluemicro builder. I have an issue running the workflow. Upon running a workflow it fails with the following error:

This request has been automatically failed because it uses a deprecated version of actions/upload-artifact: v2. Learn more: https://github.blog/changelog/2024-02-13-deprecation-notice-v1-and-v2-of-the-artifact-actions/

Is the workflow based on a something deprecated?

thanks

I just updated the GitHub actions to more recent versions. Let me know if they work.
