Confusing error output in case of mn2pdf.jar failure

[maxirmx]

IMHO it needs to be better formatted and/or annotated Otherwise it is very hard to understand

[CAMOBAP]

I think it will be more clear if we will order:

• mn2pdf stdout
• mn2pdf stderr
• ruby stack trace

@maxirmx how do you think?

[maxirmx]

Agree If you fix it, please add some headers/annotations/separators as well. For me the most difficult thing was to understand that this text comes from three different sources. Thank you

[ronaldtse]

Agree that every line should be prefixed so we know which line refers to which component. Thanks!

Also I have found that in there is no java in PATH it will print no error message. Just CLI and stacktrace:

I will update PR to handle this case too

Ah, now I understand what was wrong with the item 3 here: https://github.com/metanorma/packed-mn/issues/200#issuecomment-1458896300
