Breaking: #73016 - Renaming of Clipboard->printContentFromTab to getContentFromTab

See Issue #73016

Description

During the fluidification of the clipboard, it became obvious that the method printContentFromTab() doesn't describe the method correctly anymore. So it has been renamed to getContentFromTab().

Impact

This is a public method, so it could be that some unknown extension calls the old function. But as no TER extension or the core itself calls the method, no deprecation is needed.

Affected Installations

Every extension that calls Clipboard->printContentFromTab().

Migration

Change the call from Clipboard->printContentFromTab() to Clipboard->getContentFromTab().
