release.ps1: keep Gradle's warnings from stopping a piped run

Gradle prints compiler warnings on its error stream. When the script's output was piped or
sent to a file, PowerShell 5.1 took the first such line for an error and stopped the build
at step 2 (seen on the first 0.3.1 attempt). The streams are now merged inside cmd, and
only the exit code decides whether the build failed.
