Will Jones 2bfdef2624 ci: refactor node releases (#2223 )

This PR fixes build issues associated with `aws-lc-rs`, while
simplifying the build process. Previously, we used custom scripts for
the musl and Windows ARM builds. These were complicated and prone to
breaking. This PR switches to a setup that mirrors
https://github.com/napi-rs/package-template/blob/main/.github/workflows/CI.yml.

* linux glibc and musl builds now use the Docker images provided by the
napi project
* Windows ARM build now just cross compiles from Windows x64, which
turns out to work quite well.

LanceDB JavaScript SDK

A JavaScript library for LanceDB.

Installation

npm install @lancedb/lancedb

This will download the appropriate native library for your platform. We currently support:

Linux (x86_64 and aarch64 on glibc and musl)
MacOS (Intel and ARM/M1/M2)
Windows (x86_64 and aarch64)

Usage

Basic Example

import * as lancedb from "@lancedb/lancedb";
const db = await lancedb.connect("data/sample-lancedb");
const table = await db.createTable("my_table", [
  { id: 1, vector: [0.1, 1.0], item: "foo", price: 10.0 },
  { id: 2, vector: [3.9, 0.5], item: "bar", price: 20.0 },
]);
const results = await table.vectorSearch([0.1, 0.3]).limit(20).toArray();
console.log(results);

The quickstart contains a more complete example.
