STDOUT and STDERR are separated in dashboard logs

[AlexSkrypnyk]

Describe the bug

STDOUT and STDERR are separated in dashboard logs: all stdout messages printed first, then all stderr messages.

To Reproduce

Steps to reproduce the behavior:

1. Clone any example projects
2. Add error to post-deploymnent
3. Run a deployment
4. Observe that stdout messages printed and then stderr messages printed.

Expected behavior

All messages are printed consequently, as they are produced by the deployment scripts.

Screenshots

Additional context

Having errors printed separately and not in the order they appear makes it extremely hard to debug deployment errors as it is simply hard to understand where the error originated.
