docs(examples) fixes and clarifications

* docs(examples): added note that `yarn dev` should be run in repo root
* fix(examples): removed alias in examples: alias only means to be used for local runs and we use main vite config for it, and the vite config in examples is for codesandbox
* fix(examples): added asset handling of gltf and hdr for examples, both in sandbox and locally
* docs(examples): referred to contributing guide rather than have separate conflicting info
