Update chokidar to watch version.txt

[xHomu]

Update chokidar to resolve a rare race condition issue that resultant in dev server crashing. This PR remix-run/remix#7299 sets up a fix where we can watch the version.txt file for changes (rather than build/index.js directly) to avoid race condition.

Test Plan

This affects dev server behavior only.

Screenshots

In some rare circumstances, the current chokidar watch setup could result in the following error:

/.../node_modules/@remix-run/server-runtime/dist/dev.js:26
      buildHash: build.assets.version
                              ^
TypeError: Cannot read properties of undefined (reading 'version')
    at Object.broadcastDevReady (/.../node_modules/@remix-run/server-runtime/dist/dev.js:26:31)
    at FSWatcher.handleServerUpdate (/.../node_modules/@remix-run/serve/dist/cli.js:74:12)

We sidesteped this race condition issue by introducing a new file in Remix v2, version.txt, that only gets updated after the build completes.

Ops, chokidar should be a devDependency now.
