Support ng-content inside the astro-angular package about analog

[seeplusplus]

@thebspin A good place to start might be here
https://github.com/analogjs/analog/blob/beta/packages/astro-angular/src/server.ts#L76-L82
There is an unused _children property on this function. See here where that same property (called slot) is being used.

It doesn't look like any of the Angular functions being called in the rest of renderStaticMarkup can accept children/slots but there is this method in @angular/core:

https://github.com/angular/angular/blob/e02bcf89cf77c3118c649a7db68e66a78f16155c/packages/core/src/render3/component.ts#L73

However this requires an EnvironmentInjector. I think these might be the pieces needed, but I'm not sure how to put them together

Thanks, today i had some time and tried this route (seems the most logical) but unfortunaly when calling the createComponent function i get an Angular error i have yet to solve.
NG0407: Angular was not able to inject a renderer (RendererFactory2). Likely this is due to a broken DI hierarchy. Make sure that any injector used to create this component has a correct parent.
I do pass the bootstrap.injector as an option and that should work but it doesn't..

EDIT: it's probably because bootstrap.injector is empty, where bootstrap is the result of the bootstrapApplication function that's already in place
