action-slack: Job information cannot be obtained if the job is renamed.

Describe the bug About two weeks ago the job field of our Github Action reports in Slack changed to report “Job is not found. Check the matrix.” The Action configuration has not changed in that time. To our knowledge nothing related to the Github Action or our git workflow or team activity has changed.

Expected behavior The expected behavior is the Slack message produced by the action to include the job name from the Githhub action configuration.

Screenshots Here is a sample report in Slack before the behavior changed.

Here is a sample report in Slack after the behavior changed:
