generate input/output bindings to the GridJS package

It all started when I saw this comment:

 // TODO: auto generate Inputs/Output to easily sync with grid-js main package

I spent several hours trying to figure out how to accomplish this, and after looking at the implementation of https://github.com/microsoft/ts-gyb, I tried writing my own script for transforming the GridJS TypeScript interfaces into something we could use in this library for input/output bindings on the Angular component.

The script that does the heavy lifting is at scripts/update-bindings.mjs and is executed by calling nx update-bindings gridjs-angular. The script uses the TypeScript package to get type information from node_modules/gridjs/dist/src/events.d.ts (where GridEvents is defined) and node_modules/gridjs/dist/src/config.d.ts (where Config is defined), collecting the data we need into an object. That object is then passed to MustacheJS which transforms the data into a TypeScript class. I specifically didn't want the main library component file to be auto-generated (as it's more painful to make changes to a template), so I tried to keep the generated code to bindings only, and members that require the names of all the properties from either Config or GridEvents. Thus the output file is an abstract class with all the @Input() and @Output() decorators (the boilerplate). Then the main export of the library, GridJsAngularComponent, extends the base class and handles any other custom things needed for the Angular wrapper.

I also made sure that the generated code uses Angular Signals, which should help with at least near-term future-proofing of the library.

Finally, I cleaned up some things that didn't need to be there (like the empty routes file and accompanying router-outlet) and spruced up the Readme. I also expanded the demo to use more of GridJS's features to make it a better sample of the library's usage.

I'm eager to do some unit testing, but this PR is already getting pretty large and disruptive so I'd prefer to add those in a separate PR.

I tried to maintain backwards compatibility by adding that alias for the gridLoad event (not sure if it works due to this GridJS issue, but at least the rowClick/cellClick events work so I assume it should be OK).

Please, provide as much feedback as necessary. Hoping this moves the library forward in a positive way!

One more note: while testing I saw some console errors, but it doesn't seem like it's related to anything in this library (see grid-js/gridjs#1291)

Also, noticed that the nx format:check command is failing, but I don't agree with how it wants to fix some things:

Not sure if this is just some workspace formatting settings that need to be changed, but I'm unsure what to do about it.
