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

-### API
-
-#### `> libnpmdif([ a, b ], [opts]) -> Promise<String>`
-
-Fetches the registry tarballs and compare files between a spec `a` and spec `b`. **npm** spec types are usually described in `<pkg-name>@<version>` form but multiple other types are alsos supported, for more info on valid specs take a look at [`npm-package-arg`](https://github.com/npm/npm-package-arg).
-
-**Options**:
-
-- `color <Boolean>`: Should add ANSI colors to string output? Defaults to `false`.
-- `tagVersionPrefix <Sring>`: What prefix should be used to define version numbers. Defaults to `v`
-- `diffUnified <Number>`: How many lines of code to print before/after each diff. Defaults to `3`.
-- `diffFiles <Array<String>>`: If set only prints patches for the files listed in this array (also accepts globs). Defaults to `undefined`.
-- `diffIgnoreAllSpace <Boolean>`: Whether or not should ignore changes in whitespace (very useful to avoid indentation changes extra diff lines). Defaults to `false`.
-- `diffNameOnly <Boolean>`: Prints only file names and no patch diffs. Defaults to `false`.
-- `diffNoPrefix <Boolean>`: If true then skips printing any prefixes in filenames. Defaults to `false`.
-- `diffSrcPrefix <String>`: Prefix to be used in the filenames from `a`. Defaults to `a/`.
-- `diffDstPrefix <String>`: Prefix to be used in the filenames from `b`. Defaults to `b/`.
-- `diffText <Boolean>`: Should treat all files as text and try to print diff for binary files. Defaults to `false`.
-- ...`cache`, `registry`, `where` and other common options accepted by [pacote](https://github.com/npm/pacote#options)
-
-Returns a `Promise` that fullfils with a `String` containing the resulting patch diffs.
-
-Throws an error if either `a` or `b` are missing or if trying to diff more than two specs.
