feat(vercel): Use Sharp in dev instead of Squoosh by default (#8445)

* feat(vercel): Use Sharp in dev instead of Squoosh by default

* fix(build):

* nit: adjust with feedback

* fix: imports

* Update packages/integrations/vercel/README.md

Co-authored-by: Sarah Rainsberger <sarah@rainsberger.ca>

* docs: small change in other part of the README

### devImageService
**Type:** `'sharp' | 'squoosh' | string`<br>
**Available for:** Serverless, Static
**Added in:** `@astrojs/vercel@3.3.0`
**Default**: 'sharp'
Allows you to configure which image service to use in development when [imageService](#imageservice) is enabled. This can be useful if you cannot install Sharp's dependencies on your development machine, but using another image service like Squoosh would allow you to preview images in your dev environment. Build is unaffected and will always use Vercel's Image Optimization.
It can also be set to any arbitrary value in order to use a custom image service instead of Astro's built-in ones.
```js
import { defineConfig } from 'astro/config';
import vercel from '@astrojs/vercel/serverless';
export default defineConfig({
output: 'server',
adapter: vercel({
imageService: true,
devImageService: 'squoosh',
}),
});
```
