Meta: GitHub ActionsI fails at the very early stage when invoked from non-maintainer's pull request

[konn]

After merging 7fa3ff6 into my branch konn/expand-splice--lugin, which is a base branch for P.R. #759 , it seems that CIs on GitHub Actions accidentally stop to work at the very first stage, with the following error:

  Error: Resource not accessible by integration

Seems like some kind of an access control issue, or perhaps just an upstream glitch.
