doc: zlib createGzip doesn't provide an example of usage.

[RamirezAlex]

I noticed that the documentation zlib.createGzip() doesn't have an example of how to use it and it would be nice to have one example like many others on the Node.js docs.
https://nodejs.org/api/zlib.html#zlib_class_zlib_gzip

I am willing to help to provide examples for the zlib documentation.

The very first example in the doc uses it.

const gzip = zlib.createGzip();
const fs = require('fs');
const inp = fs.createReadStream('input.txt');
const out = fs.createWriteStream('input.txt.gz');

inp.pipe(gzip).pipe(out);

That's not necessarily a reason to not include an example where the function is described. (But maybe it is?)
