[#417] Support sovereign / national clouds

[ceciliaavila]

Fixes #417

Description

This PR contains the changes to make the authority endpoint configurable, allowing the use of national clouds in CopilotStudioClient and Agents-Hosting packages.
The default value is the public cloud URL: https://login.microsoftonline.com.

Detailed Changes

• Added the authorityEndpoint property in:
  • ConnectionSettings
  • copilotStudioConnectionSettings
  • authConfiguration
• Replaced hard-coded values with the value read from the configuration in msalTokenProvider and jwt-middleware
• Updated unit tests to verify the correct population of the property in authConfiguration.test.ts
• Updated copilotstudio-console and copilotstudio-webchat samples to use the authority from the settings.

Testing
