runtime-extra-platforms pipeline is broken

[vcsjones]

The runtime-extra-platforms pipeline is erroring and not running at all.

Stage Build job build_android_x64_Release_NativeAOT appears more than once. Job names must be unique within a stage.

Example: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1120047&view=results
