Update Slack notification to mention @hub-team instead of @channel

[yogendrasinghx]

This PR updates the GitHub Actions workflow to change Slack notifications from @channel to @hub-team. By mentioning @hub-team, we ensure that only the relevant team members are notified when actions fail or are cancelled.

Additional Notes

• Please ensure that the HUB_TEAM_SLACK_ID secret is correctly set in the repository settings
• No other changes were made to the workflow beyond the Slack notification update
