v5.0.0

- Build lib on top of Node.js `fetch`, drop `node-fetch` (#26)
- Bump version of rimraf

The switch to `fetch` is breaking in that Node.js v18 or greater is now
required. Also, depending code may need to be adjusted if it relied on the
`Response` being the one from `node-fetch`, and not the one defined in Fetch.
