use rollup

Got errors saying Module not found when trying to update polkadot.js app PR with latest version. Tried a few fix with swc setup, but did not make it work.

Then I checked a few packages with dual bundle, I tried to just follow vite-node’s solution: https://github.com/vitest-dev/vitest/blob/main/packages/vite-node/rollup.config.js, it seems all work fine

Tests

• [x] run cli
• [x] e2e
• [x] web-test
• [x] playwright-test
• [x] polkadot.js app
• [x] mangata-e2e

webpack thing { test: /\.m?js$/, resolve: { fullySpecified: false, // disable the behaviour }, },
