This PR updates everything for 2027. This includes removing GradleRIO, simplifying our wpilib version defintion, updating APIs, updating to Java 21, and more.
Note that photonlibpy is failing because robotpy has not been fully updated yet. Examples are omitted because they need to be updated for our new PhotonPoseEstimator API and still need some changes from WPILIB. photonlib windows build is failing because we're waiting for some upstream changes. Finally, images are failing since they don't have Java 21 yet.
## Description
This bumps our actions to versions that use Node 24, instead of 20. Node
20 [enters EOL in April 2026](https://endoflife.date/nodejs).
This PR also includes various cleanups that should speed up CI, and make
it less complicated. This includes removing the architecture field from
setup-java, as it detects the native architecture.
We also upload our Gradle dependencies for charting in GitHub, this
helps us keep track of what we're using, and if we need to upgrade.
Finally, we bump the version of our image, to fix issues with the Rubik
Pi fan among other reasons.
