Fixes#1564. Also copies vendordep JSONs to the examples as advised by
Thad. Removes unused shared/javacpp/setupBuild.gradle. Also removes
unnecessary `chmod +x gradlew` from CI workflows.
Reverts PhotonVision/photonvision#1375
Causes white screen UI Bug, "the way we currently strap everything with
vue2 and vuetify has a lot of footguns in it, and using a newer package
manager where each subdependency gets its own version of node is causing
incorrect dependency resolution which also means we can't fix this
without either updating node or patching those dependencies id say just
revert the PR for now until I or someone else can do the vue3 update"
Pnpm is like npm except instead of keeping multiple copies of
dependencies, it shares a single copy for multiple dependencies
significantly reducing build time and the space needed to hold all the
dependencies. Read [here](https://pnpm.io/motivation) for more info.
This changes our CI to use pnpm and allows developers to choose to use
pnpm instead of npm. Also, pnpm has a built-in node version manager so
devs no longer need to use nvm to work on photonvision. All npm
functionality (including photon-server gradle tasks) still functions
using npm so this isn't breaking. We should make a docs change to
suggest to use pnpm.
