Release workflow fails when identifying related PRs

[stempler]

The release workflow currently fails at one point in the github plugin, where the release success is handled.
Because all important steps (create git tag, create github release, publish release artifacts) are done before, this is not a critical issue.
However, it seems to prevent comments on PRs and issues that the changes were released.

It seems to fail here when determining the PRs related to the release.

More verbose logging of semantic-release was enabled in #160 (verified in dry run), hope we can get some more insights on the next actual release run.
