node-pre-gyp setup

The current node-pre-gyp setup is incorrect, the binary host points to the docs instead of a place where the built binaries are stored.

Things to do to improve the usage:
- [ ] Set up a CI on Mac OS and Linux (glibc and musl builds?) to build the binaries.
- [ ] Use [node-pre-gyp-github](https://github.com/bchr02/node-pre-gyp-github) tool to upload the built binaries to GitHub releases, so that users can download the binaries during install.
- [ ] This project uses N-API, so the default binary name can be optimised to not include node ABI version in it. This will allow to build a single binary per platform without the need of building it for every node version. `"{module_name}-{version}-{platform}-{libc}-{arch}.tar.gz"`

Start by reviewing the current node-pre-gyp setup and how its binary host and naming template are configured. Then examine the proposed node-pre-gyp-github flow and determine the CI matrix for macOS, Linux glibc, and Linux musl builds. Done means binaries are built, uploaded to GitHub releases, and downloadable during installation with the N-API-compatible name.
