Make deploying the web searcher plugin optional (#517)

### Motivation and Context

<!-- Thank you for your contribution to the chat-copilot repo!
Please help reviewers and future users, providing the following
information:

-->
The Web Searcher plugin requires a Bing resource, which may require
elevated permission. This will fail the whole deployment, blocking
developers from deploying the latest CC.

Issues:
#498

### Description
This PR makes deploying the Web Searcher plugin optional. And by
default, it's NOT deployed.
