do not allow individual commands to close the top-level OutputStream (System.out)

[StevenMassaro]

Impact

• Bug fix (non-breaking change which fixes expected existing functionality)
• Enhancement/New feature (adds functionality without impacting existing logic)
• Breaking change (fix or feature that would cause existing functionality to change)

Description

This change prevents individual commands from closing the output stream they are provided, which is actually System.out. It is bad practice for code to close System.out particularly because other command steps will still expect it to be open.

Things to be aware of

Things to worry about

In very unusual circumstances, we might get more output than we did initially, because commands called after the RegisterChangelogCommandStep previously had a closed output stream. This isn't really a worry, and more of a positive thing.
