Replace through2 with node:stream

[talentlessguy]

From through2 GitHub repo:

Since Node.js introduced Simplified Stream Construction, many uses of through2 have become redundant. Consider whether you really need to use through2 or just want to use the 'readable-stream' package, or the core 'stream' package (which is derived from 'readable-stream'):

const { Transform } = require('readable-stream')

const transformer = new Transform({
  transform(chunk, enc, callback) {
    // ...
  }
})

In fact, there's no need to use readable-stream either, it can be replaced straight up with node:stream.

Here's a list of top 50 packages depending on through2:
