Move partiql-playground to Node.js (#177)

* Move partiql-playground to Node.js

This is the first PR as part of a series of PR to new features in PartiQL Playground:

This PR includes the following:

- Moves the PartiQL Playground to a Node.js project. This allows
using the Node features within the project, such as having a
server side listerner instead of an arbitrary web-server.

- Removes the `ace-builds` sub-modules as an action from previous reviews.

TODO:
[x] Node.js server listener
[x] Remove `ace-builds` submodule.
[] Containerization
[] Client side URL export
[] AST Graph pan and zooming bugfix
