Similar or Duplicate pages for ModuleData

[sypets]

Current behavior

The following pages are similar or almost the same:

• https://docs.typo3.org/m/typo3/reference-coreapi/main/en-us/ExtensionArchitecture/HowTo/BackendModule/ModuleDataObject.html (in Extension Architecture / How section)
• https://docs.typo3.org/m/typo3/reference-coreapi/main/en-us/ApiOverview/RequestLifeCycle/RequestAttributes/ModuleData.html in request life cycle

Expected behavior/output

Perhaps it is possible to reduce the content on the "request lifecycle" page and refer to the other page.

Also, on the request life cycle page, the part for how to access the module data is missing. Since it does not really refer to the other page, the information is incomplete.

$request->getAttribute('moduleData');
