fix(@angular-devkit/build-angular): correctly load dev server assets with vite 4.4.0+

The underlying development server (Vite) for the application build system updated
its static file serving dependencies which resulted in the `@fs` special file URLs
supported by Vite to have a different format.  Previously, the paths were encoded
using `encodeURIComponent` but are now use `encodeURI`. The development server
integration with Vite will now use the matching encoding to allow build defined
assets to be correctly served.
