Add browser-esbuild builder

[Klaster1]

Motivation:
The application builder always creates browser dir in the build target directory, breaking the deployment pipeline. The official recommended way is to use the browser-esbuild, however, dotenv-run doesn't wrap that particular builder.

Suggestion:
Wrap and expose the browser-esbuild builder in the same manner as the application builder.

OK, I am stupid for not reading until the thread end. The desired result can be achieved with @angular-devkit/build-angular 17.1. Sorry for bothering you, close the issue if you feel like it.
