Welcome page extension suggestions should not be hardcoded into our source code

On the welcome page, we hardcode some recommended extensions for the Tools and languages section.

The problem with making this configurable is / might be that the UI doesn't scale well, so one has to be careful not to put too many extensions in.

Do you have a specific use case in mind?

[mjbvz]

When I updated our recommendations to recommend the new tslint-plugin extension instead of the eg2.tslint extension, I missed updating the reference to the old tslint extension on the welcome page.

Also I don't think we should be referencing VS marketplace extensions in OSS builds

No longer using that list. We do have the SVG's of extensions with clickable links, I suppose we could pull those into -distro a la. the other product images. cc @digitarald @misolori

[miguelsolorio]

Do we need to move all of the walkthroughs over to distro then? The only items that would be applicable to the marketplace is extensions and there's a few spots where we mix those in.

[JacksonKearl]

Hm, I think this could be a good use case for product-specific tiles, as we want to avoid any code patches in distro going forward.... some sort of product.json/embedder API to provide additional tiles would be nice to have here.

We no longer recommend extensions in the welcome page.
