Test failure related to fetching fuel models

[scpeters]

Environment

• OS Version: Ubuntu 20.04 CI
• Source or binary build? using gazebo11 branch from source as of 5fef8ee

Description

• Expected behavior: CameraSensor.CheckNewAndLegacyDistortionModes should pass
• Actual behavior: test started failing on Dec 7, 2022 with console messages related to fuel model downloads and some timeouts when expecting models to load in a certain amount of time.

Steps to reproduce

1. Build gazebo11 from source
2. Run INTEGRATION_camera_sensor test

Output
