fix(@angular/build): allow tailwindcss 4.x as a peer dependency

To support usage of the newly released Tailwind CSS 4.0.0, the peer dependency
range has been update to include `^4.0.0`. This prevents potential installation
warnings/error when using various package managers.
Use of Tailwind CSS 4+ requires either the `application` (new project default) or
`browser-esbuild` builder. Both of which support custom postcss configuration
via a `.postcssrc.json` file.

For instructions on the setup of Tailwind CSS with Angular, please see the
Tailwind CSS documentation here: https://tailwindcss.com/docs/installation/framework-guides/angular
