fix(examples): update kitchen-sink dev task (#4177)
### Description
When running `dev` before running a `build`, the packages won't be built
when the apps needed them.
This fixes this by adding:
`"dependsOn": ["^build"]` on `dev` to enforce the correct `build` order
_first_ (to make sure the `dev` script can run successfully every time),
and then running `dev` to kickoff the watch processes in each workspace
### Testing Instructions
`pnpm dev`
