build: update release config to reflect latest ng-dev config changes

The ng-dev release config changed its release configuration in order
to support experimental packages. This commit updates the FW release
config to work with the new config signature of ng-dev.

All of our peackages are non-experimental, so we do not specify
an explicit `experimental` property.
