fix(amplify-gen2-migration-e2e-system): pipe amplify push output unless debug

Only inherit stdio for amplify push when the logger is in debug
mode. Otherwise pipe stdout/stderr to keep non-verbose runs
quieter. Adds Logger.isDebug() helper.

Prompt: I made another code change, commit and update the pr
file.
