CinemachinePathBase.FindClosestPoint doesn't search the last segment of its path when there are more than 2 segments

How to reproduce:
1. Open the user-attached “PathClosestPoint LatestPatch.zip” project
2. Open the “SampleScene” Scene
3. Select the “Sphere” GameObject in the Hierarchy window
4. Enter Play Mode
5. Note the “Nearest Point” value of the Script component

Expected result: The “Nearest Point” value is 3
Actual result: The “Nearest Point” value is a fraction value

Reproducible with: 2.6.17 (2020.3.43f1), 2.8.9 (2020.3.43f1, 2021.3.16f1), 2.9.4 (2020.3.43f1, 2021.3.16f1, 2022.2.1f1), 3.0.0-pre.3 (2022.2.1f1, 2023.1.0a24)

Reproduced on: macOS Monterey 12.6 (Intel), Windows 10 64bit - User Reported

Edit: The “Nearest Point” fraction value might be ~2.013 and or higher when testing
