Error: Resource not accessible by integration

I get this error in pull-requests made by @dependabot

```
Run bcoe/conventional-release-labels@v1
with:
token: ***
type_labels: {"feat": "feature", "fix": "fix", "breaking": "breaking"}
ignored_types: ["chore"]
ignore_label: ignore-for-release
Error: Resource not accessible by integration
```

Start by examining the pull-request workflow that invokes bcoe/conventional-release-labels@v1 and the token passed to it, focusing on how Dependabot-triggered runs differ. Reproduce the error on a Dependabot pull request and confirm that the action can apply the configured labels without the integration access failure.
