Description

What changed?

Alternative to #2670 that requires the CameraServer/AprilTag vendordeps directly instead of their Maven artifacts. This requires the CameraServer/AprilTag vendordeps to be manually installed, but prevents hard-to-understand error messages from version conflicts.

Why?

GradleRIO alpha-8 stopped preinstalling the vision libraries.

If a vendordep is missing, an error like the following is printed:

> Failed to apply plugin class 'org.wpilib.gradlerio.wpi.WPIPlugin'.
   > Could not create an instance of type org.wpilib.gradlerio.wpi.WPIExtension.
      > Conflicting Vendor Dependency 19049c8a-7635-4aca-aa7d-1fdde2c10eed for uuid 515fe07e-bfc6-11fa-b3de-0242ac130004. Reason: You need to install the CameraServer vendordep from WPILib!

If a conflicting version is found (as can be the case in the other PR), a vague error message like the following is displayed:

> Entry libopencv_videoio.413.dylib is a duplicate but no duplicate handling strategy has been set. Please refer to https://docs.gradle.org/9.4.1/dsl/org.gradle.api.tasks.Copy.html#org.gradle.api.tasks.Copy:duplicatesStrategy for details.

It might be worth figuring out what the resolution to wpilibsuite/allwpilib#9700 is first before deciding between these two PRs, because if OpenCV is given a custom version alias I think #2670 would give a better user experience.
