Corrects fisheye camera projection types in spawner configuration

[command-z-z]

Description

This MR fixes the support of fish-eye projection type. Actually, I don't find the proper fisheye type on Replicator camera website (maybe it's out of style).

I only check the cameraProjectionType in Raw USD Properties in Isaacsim GUI.

Fixes #1331
