Remove code to delete the tsconfig for ui extensions

[vividviolet]

WHY are these changes introduced?

New extensions should always have a typed shopify global according to the specified target. We no longer need to delete the tsconfig. This change is also needed to support non-preact templates like data extensions that only has a .js file.
