Fix: XML whitespace trims while pretty print

[bharath2203]

Description

The above PR resolves the bug which causes the XML element with whitespace in the left or right to be trimmed after passing the variable through karate.log or print.

The idea of the fix is to clone a temporary node while serializing the XML node to string in case of pretty print, as the code trims the whitespace of the element while pretty printing and does that directly on the object itself causing it to change.

Issue: #2385

Thanks for the work on this. I can see that the act of logging will not change the xml. I do think though that the pretty printing should preserve the whitespace within an xml element value, as it is significant. What you see in the log would not be the correct element value when the whitespace has been stripped. In XmlUtilsTest line 238 the expected value should be:

• " moo \n"
