Is your feature request related to a problem? Please describe.
The output from tasks is hard to read since new lines are ignored.
To better read the output let's put it in a code block and respect white space characters.

Would also be nice to have a quick copy button to copy the whole output text.

Describe the solution you'd like
Modify the task output component to contain output in a code block, respect white space, and offer a copy option

Describe alternatives you've considered
