Failure on self-hosted runners

[shaharshitrit]

Hi,

When executing the merge-gatekeeper on self-hosted runner I'm phasing the following error: Build container for action use: '/runner/_work/_actions/upsidr/merge-gatekeeper/v1.2.1/Dockerfile'. Error: Docker build failed with exit code 1

In order to avoid this error, I need to implement one of the following:

1. find a way to authenticate the docker commands
2. Execute the merge-gatekeeper workflow on GitHub managed runners instead of my org self-hosted runners.

There's a simple solution or guidelines for the first option?
