RFR: 8307480: Improve SA "transported core" documentation for windows [v3]

[Chris Plummer]

> The SA document `transported_core.html` contains some tips on getting core files to work when debugging it on a machine other than the one that produced it. There are a few improvements that can be made based on information provided in [JDK-8306437](https://bugs.openjdk.org/browse/JDK-8306437) and in the #13530 review (which was eventually pulled as not necessary).
> 
> Updates to the document include the use of `sun.jvm.hotspot.debugger.windbg.imagePath` and `sun.jvm.hotspot.debugger.windbg.symbolPath` properties, and adding "`srv*https://msdl.microsoft.com/download/symbols`" to symbolPath.
> 
> The rendered html file with these changes can be found here:
