[#382] Fix Warnings in api-docs pipeline

[ceciliaavila]

Fixes #382

Description

This PR fixes the error JSDoc issues causing warnings in the typeDoc check.

Detailed Changes

• Removed the TurnContext interface. This interface was empty and unused, leading to ambiguity in TypeDoc.
• Re-exported the TurnContext type in agents-hosting-dialogs/src/index.ts because it wasn't resolving the docs correctly.
• Removed env as language identifies in agents-copilotstudio-client/README.md, as it wasn't supported.
• Fixed @link references in different files.
• Added missing exports in index.ts files
• Removed unsupported tags @const and @mention from comments.
• Removed outdated @param comments.

Testing
