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.

-# promise-call-limit
-
-Call an array of promise-returning functions, restricting concurrency to a
-specified limit.
-
-## USAGE
-
-```js
-const promiseCallLimit = require('promise-call-limit')
-const things = getLongListOfThingsToFrobulate()
-
-// frobulate no more than 4 things in parallel
-promiseCallLimit(things.map(thing => () => frobulateThing(thing)), 4)
-  .then(results => console.log('frobulated 4 at a time', results))
-```
-
-## API
-
-### promiseCallLimit(queue Array<() => Promise>, limit = defaultLimit)
-
-The default limit is the number of CPUs on the system - 1, or 1.
-
-The reason for subtracting one is that presumably the main thread is taking
-up a CPU as well, so let's not be greedy.
-
-Note that the array should be a list of Promise-_returning_ functions, not
-Promises themselves.  If you have a bunch of Promises already, you're best
-off just calling `Promise.all()`.
-
-The functions in the queue are called without any arguments.
