Remove the 'debug' versions from the SSI package to reduce its size

[iamluc]

Description

With the release of the version 1.5.0 (and the addition of PHP 8.4), we exceed the limitation of 120MB we set for the Kubernetes injection image.

Let's remove the debug versions that should not be used except in a local dev environment.

Reviewer checklist

• Test coverage seems ok.
• Appropriate labels assigned.
