Could you add a Packagist entry, this just takes a few minutes if using github. If configuring the github integration it's a "configure once, will update automatically" solution.
GitHub Service Hook
Enabling the Packagist service hook ensures that your package will always be updated instantly when you push to GitHub.
To do so you can:
Go to your GitHub repository
Click the "Settings" button
Click "Integrations & services"
Add a "Packagist" service, and configure it with your API token, plus your Packagist username
Check the "Active" box and submit the form
You can then hit the "Test Service" button to trigger it and check if Packagist removes the warning about the package not being auto-updated.`
