Build/Test Tools: Increase timeout value for Slack message jobs.

Because of how dependent jobs and queuing works in GitHub Actions, it’s common for workflows to be completed with the exception of sending Slack notifications.

“The waiting is the hardest part”, and occasionally these jobs hit the `10` minute timeout value before their turn comes up.

See #62221.
