feat(site): add copilot as a provider option in AI Bridge logs filter (#22023)

## Problem

The Copilot provider was missing from the AI Bridge logs filter dropdown, so users couldn't filter interceptions by Copilot. Additionally, the `AIBridgeProviderIcon` component didn't handle the copilot provider, so it would render a fallback question mark icon.

## Changes

* Added `copilot` case to `AIBridgeProviderIcon`, using the existing `/icon/github.svg`.
* Added Copilot as a provider option in the filter dropdown.
* Added `MockInterceptionAnthropic` and `MockInterceptionCopilot` mock data with sample prompts, and updated the Storybook stories to use one interception per provider.
