Capacitor is now forcibly installed on starter projects

Description:
There used to be a prompt to add capacitor to a new project created using the starter templates, but that option no longer is shown and it's added by default to all projects whether you want it or not. For web based projects, Capacitor isn't needed. Sure, it's easy enough to remove it afterwards, but a bit of a pain and all the dependencies are installed too, so really have to delete node_modules and reinstall from scratch to fully remove it. Same behavior using the new wizard on the web too.

Steps to Reproduce:
Run ionic start, pick Angular, pick and template, and capacitor is added without any prompt

My ionic info:

Ionic:

   Ionic CLI : 6.17.0

Utility:

   cordova-res                          : 0.15.3
   native-run (update available: 1.4.0) : 1.3.0

System:

   NodeJS : v14.17.4
   npm    : 6.14.14
   OS     : macOS Big Sur

先使用 ionic start 重現此行為，選取 Angular 和一個 starter template，接著追蹤 starter-project generation flow 以及相應的 web wizard path。完成標準是再次提供 Capacitor 選項，且 web projects 除非選取該選項，否則不會安裝 Capacitor 或其相依套件。
