is it possible to generate that path at runtime (like in the entrypoint ? )

because this is not always /projects, it's $PROJECTS_ROOT

Yes, now it is possible to provide the default configuration with variables using static/default-configuration-provider.sh
The xml configuration moved from the files to variables and now it is possible to use the $PROJECTS_ROOT in particular values. Environment variables will be extracted on the file creation step.

The content of generated some config file in runtime:

While it has raw content:

<application>
     <component name="Trusted.Paths.Settings">
         <option name="TRUSTED_PATHS">
             <list>
                 <option value="$PROJECTS_ROOT" />
             </list>
         </option>
     </component>
 </application>

LGTM
but it would be nice to have separated the code refactoring from the actual patch that fixes the issue (next time 😉)
