Nicely format build.xml

[rjkip]

The build.xml that is currently written is not properly indented everywhere. Would be nice to put it through DOMDocument (for example) for some reformatting. Verify that this indeed creates more legible XML. When reformatting fails due to e.g. syntax errors, a rollback must occur.

Code to pretty print XML:

$xml = simplexml_load_string($contents);
    
$dom = new DOMDocument();
$dom->formatOutput = true;
$dom->preserveWhiteSpace = false;
$dom->loadXML($xml->asXML());
$newContents = $dom->saveXML();
$contents = $newContents;

The idea was to insert it somewhere before this line:

qa-tools/src/Core/Task/Executor/AddBuildTaskExecutor.php

Line 110 in 1ef6032

$this->fileHandler->writeWithBackupTo($buildFile, $contents);

The question is how much tests will fail because if this. If too many break we may need to search for an alternative, like a separate task.
