name: Build Release Installers

# Builds Windows and macOS installers when a release is published and
# attaches them to it. macOS builds are signed and notarized only when the
# runner has the Developer ID identity and the APPLE_API_ISSUER and
# APPLE_API_KEY_P8 secrets are set; otherwise they are ad-hoc signed.
