fix(@angular/build): exclude JSON imports from Vite dependency optimization

Importing `.json` files (such as package.json files from third-party packages)
causes Vite's dependency optimizer to throw errors and warnings during
`ng serve`, as Vite is unable to optimize non-JS/TS modules:

`Cannot optimize dependency: @pkg-name/package.json, present in client 'optimizeDeps.include'`

This fix filters out any implicit dependencies ending in `.json` in the
`updateExternalMetadata` utility, preventing them from being included
in Vite's `optimizeDeps.include` array.

Closes #33280
