Add Support of Work Item attachements / images

[fien002]

I would like to have support for work item attachchments in the azure devops mcp server.
A tool like "wit_get_work_item_attachement" would be great, because we're heavily using the screenshots for example for bug creations. As github copilot is supporting media attachements (png, ..) it would be very helpful if it could access the work item attachement to get the whole context of the item.

When it uses "wit_get_work_item" it only get the URL to the attachement (image) in the work item description.

Summary

Implement two new tools that integrate with Azure DevOps APIs to enable search capabilities.

Tools

Develop the following tools with full parameter support, including optional ones:

wit_get_work_item_attachement: Search Azure DevOps Wikis for relevant content.

Endpoint: POST https://almsearch.dev.azure.com/{organization}/{project}/_apis/wit/attachments/{attachmentId}?fileName={filename}

Rules

1. Adhere strictly to existing project standards and coding conventions.
2. Ensure each tool exposes all API parameters (required and optional).
3. Use the official Azure DevOps Node API to interact with the APIs.

Special treat

If you follow the rules, you'll get candy!

Historically this is not something we plan to do. If you would like to create a PR for us to review, we are open to that.

Moving this to discussion. But feel free to create a PR. Keeping in mind simple is better.
