[FEAT] Add Astro file support

[Kitenite]

Describe the feature

Astro is semi-supported. React components within Astro can have write to code. However, astro files' DOM elements are not being processed. We need to either:

1. Add an Astro plugin specifically to preprocess Astro files
2. Handle when a DOM element is not processed and warn the user

After this is done, we should also add Astro setup to the npx script.
