------------------------------+--------------------
 When running a command that goes via docker.js -- for example the PHP unit
 tests with `npm run test:php` or a WP-CLI command with `npm run env:cli`
 -- a rather verbose and unnecessary error message and stack trace will be
 shown by Node.js at the end of the output if the target command produces a
 non-zero exit code.

 This can safely be hidden because the stack trace only points to the
 `execSync()` call and is of no use.

 Let's hide it with a try catch block. The prior output from the target
 command remains visible.
