Volumes set to triggers should be excluded from navmesh generation as there's no real reason to need it. It actively harms regular use cases, causing confusion and breaking nav pathing, or requiring navmeshmodifiers on each trigger to be manually ignored.

Reproduction steps:
1. Open the attached ‘NavMeshSurfaceIncludesTriggersRepro’ project
2. Open the ‘Repro’ Scene
3. Observe the ‘NavMeshSurface’ GameObject in the Inspector
4. Click on the ‘Bake’ button in the ‘NavMeshSurface’ component

Expected result: The NavMesh is not generated on the GameObjects with the 'Is Trigger' Box Coliider
Actual result: The NavMesh is generated above the ‘Cube Trigger’ GameObject

Reproducible with: 1.0.0-exp.4 (2020.3.35f1, 2021.3.5f1, 2022.1.9f1), 1.1.0-pre.1 (2022.2.0a18, 2023.1.0a2)

Reproduced on: macOS 11.6 (Intel)
