Broken links in documentation

[letmehateu]

Problem

The file scratch-deploy.md mentions an outdated link 3 times that works via a redirect but does not directly link to the current location.

Reason

The link uses an old URL that automatically redirects to the new location, creating an additional click.

Solution

Update the link to a direct, current URL without a redirect to improve the user experience.
Impact: Users will experience faster navigation and avoid potential issues if the redirect stops working in the future.
