Sequencer Batch Rendering cannot output multiple render passes in CLI

Batch rendering still works if launched from the engine using Sequence Render Movie. However it only outputs the first CustomRenderPass argument when attempting it from a Command Line Interface. This is a regression from 4.20.3 (CL-4369336).

This was reported and tested in 4.21 (CL-4541578). This was reproduced in Main 4.22 (CL-4594480)

1. Download the attached zip file and extract the contents to an accessible location
2. Edit the .bat file to have the updated locations of the included files
3. Run the .bat file

Results: AmbientOcclusion is the only one rendered

Expected: AmbientOcclusion, BaseColor, FinalImage, and CustomDepth should be rendered
