[TASK] Disable E_NOTICE in error_reporting

[SvenLie]

When using the PlantUML-Renderer a notice is triggered by tempnam(). This is displayed within the rendered documentation.

I think we should address the notice and not suppress it generally. Can you mention the notice here so that we can try how to prevent a notice somehow?

[SvenLie]

with following guides.xml config:

  <extension
            class="\phpDocumentor\Guides\Graphs\DependencyInjection\GraphsExtension"
            renderer="plantuml"
            plantuml-binary="/usr/bin/plantuml"
    />

Above the plantuml then this is rendered:

Notice: tempnam(): file created in the system's temporary directory in /opt/guides/vendor/phpdocumentor/guides-graphs/src/Graphs/Renderer/PlantumlRenderer.php on line 48
