Update Form add and edit Application for piped v1

[hongky-1994]

@hongky-1994 will keep working on the UI update for piped v1

PlatformProvider; UI

Purpose

Mostly related to 2 model applications and deployment

Used in

• API call AddApplication, UpdateApplication
• For showing in Application, Deployment detail page

The source fetched to used in the drawer is come from the piped configuration

https://github.com/pipe-cd/pipecd/blob/master/web/src/components/application-form/index.tsx#L58-L80

Modification idea

• Keep it as in the application and deployment model
• Also, keep the configuration and parser for pipedv0 config the same as it is (no UI affected around that fetch)
• Make a new Add Application form/suggestion form that doesn't show any platform provider-related information
