Draft: Select CE/EE Container Scanning image in template

What does this MR do and why?

We need to build different Container Scanning images for both CE and EE.

This MR updates the Container Scanning template to set the image tag according to the following scheme:

	CE	EE
no FIPS	:5	:5-ee
FIPS	:5-fips	:5-fips-ee

Previously, only :5 and :5-fips existed. Now, we add :5-ee and :5-fips-ee.

How to set up and validate locally

I tested pipelines in my cs-ee-test test project that includes the updated template:

1. CE without FIPS (commit) includes:

   registry.gitlab.com/security-products/container-scanning:5

2. CE with FIPS (commit) includes:

   registry.gitlab.com/security-products/container-scanning:5-fips

3. EE without FIPS (commit) includes:

   registry.gitlab.com/security-products/container-scanning:5-ee

4. EE with FIPS (commit) includes:

   registry.gitlab.com/security-products/container-scanning:5-fips-ee
