chore: check less stuff into node_modules

We bundle our deps, but we don't need to bundle docs, changelogs,
editorconfigs, test coverage reports, .github workflow definitions,
lint configurations, and all the rest, which we never use.

This cuts about 10% off of our publish artifact file size.

```
$ ls -laF npm-7.16.0-*.tgz

-# extend() for Node.js <sup>[![Version Badge][npm-version-png]][npm-url]</sup>
-
-`node-extend` is a port of the classic extend() method from jQuery. It behaves as you expect. It is simple, tried and true.
-
-Notes:
-
-* Since Node.js >= 4,
-  [`Object.assign`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/assign)
-  now offers the same functionality natively (but without the "deep copy" option).
-  See [ECMAScript 2015 (ES6) in Node.js](https://nodejs.org/en/docs/es6).
-* Some native implementations of `Object.assign` in both Node.js and many
-  browsers (since NPM modules are for the browser too) may not be fully
-  spec-compliant.
-  Check [`object.assign`](https://www.npmjs.com/package/object.assign) module for
-  a compliant candidate.
-
-## Installation
-
-This package is available on [npm][npm-url] as: `extend`
-
-``` sh
-npm install extend
-```
-
-## Usage
-
-**Syntax:** extend **(** [`deep`], `target`, `object1`, [`objectN`] **)**
-
-*Extend one object with one or more others, returning the modified object.*
-
-**Example:**
-
-``` js
-var extend = require('extend');
-extend(targetObject, object1, object2);
-```
-
-Keep in mind that the target object will be modified, and will be returned from extend().
-
-If a boolean true is specified as the first argument, extend performs a deep copy, recursively copying any objects it finds. Otherwise, the copy will share structure with the original object(s).
-Undefined properties are not copied. However, properties inherited from the object's prototype will be copied over.
-Warning: passing `false` as the first argument is not supported.
