Dockerbuild is failing when running the action

[felix-bose]

Since around yesterday the action is failing to build the docker container and thus run the action itself.
If I am not mistaken there is already a pr in place (#37) to switch to a JavaScript based action.

Hi, this one looks unrelated to the docker build itself but an error when downloading dependencies from GitHub. A build worked well just now with the same dependency so I'll assume it was a transient error, can you confirm if it worked well after a retry?

This could be related to go-yaml/yaml#887

Adding a GOPROXY fixes the issue: go-yaml/yaml#887 (comment)

See falbrechtskirchinger@5784c3d for a fix.
