fix(server): Bundle the the bin file before publish NPM. BM-1083 (#3375)

### Motivation

The
[@basemaps/server](https://www.npmjs.com/package/@basemaps/server?activeTab=code)
npm package is missing the bin file for excusing the command. We need to
bundle it first before publish the package.

### Modifications

Add a bundle command before NPM publish

### Verification

Locally tested. 

- delete the `server/bin/basemaps-server.cjs`
- run `npx lerna run bundle --stream` -> Got a new
`server/bin/basemaps-server.cjs` generated.
- run `npm pack --dry-run` -> Got bin file included.
