[dpogue]

Platforms affected

iOS

What does this PR do?

Passes -allowProvisioningUpdates to the build/archive step. We are already passing it to the export step (#347) but it's also worth having it here.

What testing has been done on this change?

Testing on Ayogo's Jenkins instance and was able to successfully make an iOS build without any manual steps to set up certificates or provisioning profiles.
