Add support for TRX StdOut-Element

[markusroessler]

The action currently ignores the ../UnitTestResult/Output/StdOut-Element of TRX-Files - i.e. the output is not added to the RawOutput of annotations.
Is this feature only implemented for junit xml files? Could you implement it for trx files too?
I can provide a sample dotnet repo if needed.

I think that should be do-able. All that is needed is extend the XLST to extract /Results/UnitTestResult/Output/StdOut into /testsuites/testsuite/testcase/system-out. Example files with system-out exist already.

Any news about that feature?

I would like to bump up this one as it would help a lot. The assert messages isn't always enough and we would like to see the connect tests logs as well (without having to go to the full raw logs).
