esbuild JS API `entryPoints` now accepts array of objects

[wd-David]

This error popped up after upgrading esbuild to ^0.17.1:
error TS2339: Property 'includes' does not exist on type 'string | { in: string; out: string; }'. Property 'includes' does not exist on type '{ in: string; out: string; }'.

It turns out that JS API updated since esbuild v0.17.1:

// The previous API didn't let you specify duplicate output paths
let result = await esbuild.build({
  entryPoints: {
    // This object literal contains a duplicate key, so one is ignored
    'dist': 'foo.js',
    'dist': 'bar.css',
  },
})

// You can now specify duplicate output paths as an array of objects
let result = await esbuild.build({
  entryPoints: [
    { in: 'foo.js', out: 'dist' },
    { in: 'bar.css', out: 'dist' },
  ],
})

Need to deal with the new API and consider new use cases.

The source code uses the object type of entryPoints.
It seems it's better to use an array of objects.
