Wrap terminal commands in single quotation marks instead of backticks (#17637)

after:

Since I often copy the output commands to run in the command line, using
backticks can cause errors because, in shell, backticks mean passing the
execution result of the command inside them to the -c option. Therefore,
I replace backticks with single quotes here.

Release Notes:
- Fix display of task commands to not use backticks
