[release] src/debugAdapter/goDebug: do not log env vars additionally

We added this logging while trying to help users inspect env var
propagation when using the legacy debug adapter. All the env vars
are included as a launch parameter (`env`), so instead users can
inspect the DAP trace and this is unnecessary.

Remove this - this also pollutes the test logging.
