GpuLidarSensorTest.VerticalLidar/ogre2 failure on macOS

[scpeters]

Several tests on macOS were failing to load the ignition-rendering*-ogre2 plugin (#62), which has been fixed, but now the GpuLidarSensorTest.VerticalLidar/ogre2 test is failing:

test/integration/gpu_lidar_sensor_plugin.cc:635
The difference between sensor->Range(i * horzSamples + mid) and expectedRange is inf, which exceeds 1e-3, where
sensor->Range(i * horzSamples + mid) evaluates to inf,
expectedRange evaluates to 0.35355339059327368, and
1e-3 evaluates to 0.001.

Since #101 backported the fix to ign-sensors3, besides the test above, there's also these 2:

I just ran into this problem on Linux as well and it seems that it will be fixed with gazebosim/gz-rendering#333 (see gazebosim/gz-rendering#332 for in-depth explanation)

[darksylinc]

The PR has been merged into ign-rendering. It may be worth trying this test again to see if it's fixed on macOS

[iche033]

since the issue is reported for ign-sensors3, I backported the macOS fixes to ign-rendering3 in gazebosim/gz-rendering#339. If that looks good, we can bump the ign-rendering3 homebrew bottle version then test to see if it fixes the ign-sensors3 tests.
