Dev: Improve preview.js.

Description

I've recently updated node.js on my system and see below log now when running npm run preview:

(node:11600) [DEP0190] DeprecationWarning: Passing args to a child process with shell option true can lead to security vulnerabilities, as the arguments are not escaped, only concatenated.

To fix this warning, preview.js is rewritten to avoid using npx and shell: true. The script now directly resolve rollup's bin and runs it.

I've tested this with macOS but it should work under Windows as well.
