Maybe we should switch to https://www.npmjs.com/package/browserslist-to-esbuild instead to avoid that peer dep. The API we're using shouldn't need to use esbuild, so I think we should avoid depending on esbuild if possible to prevent potential version mismatch and unnecessarily occupying disk space.

It seems this PR broke several downstream CIs:

FAIL  playground/vue-legacy/__tests__/vue-legacy.spec.ts [ playground/vue-legacy/__tests__/vue-legacy.spec.ts ]
  Error: require() of ES Module /home/runner/work/vite-ecosystem-ci/vite-ecosystem-ci/workspace/vite-plugin-vue/vite-plugin-vue/node_modules/.pnpm/browserslist-to-esbuild@2.1.1_browserslist@4.23.0/node_modules/browserslist-to-esbuild/src/index.js from /home/runner/work/vite-ecosystem-ci/vite-ecosystem-ci/workspace/vite-plugin-vue/vite-plugin-vue/node_modules/.pnpm/file+..+..+vite+packages+plugin-legacy_vite@5.1.4/node_modules/@vitejs/plugin-legacy/dist/index.cjs not supported.
  Instead change the require of index.js in /home/runner/work/vite-ecosystem-ci/vite-ecosystem-ci/workspace/vite-plugin-vue/vite-plugin-vue/node_modules/.pnpm/file+..+..+vite+packages+plugin-legacy_vite@5.1.4/node_modules/@vitejs/plugin-legacy/dist/index.cjs to a dynamic import() which is available in all CommonJS modules.

Example: https://github.com/vitejs/vite-ecosystem-ci/actions/runs/8005338357/job/21864542117

@btea let us know if you have an idea to fix this, if not I think we should revert it for now.

It looks like browserslist-to-esbuild is ESM only, I think we need to dynamically import it.
