GitHub Server: Add Get Issue Comment Feature

Description

Implemented a new feature to retrieve GitHub Issue Comments. This feature enables fetching individual comments from issues and pull requests using unique comment IDs.

Server Details

Motivation and Context

• There was a need for functionality to individually retrieve comments from GitHub Issues and Pull Requests

• Contributes to automation of issue management and workflow improvements

How Has This Been Tested?

• Tested against actual GitHub repositories with following scenarios:
  • Retrieving existing comments
  • Error handling with invalid comment IDs
  • Comment retrieval across different repositories

Breaking Changes

• No breaking changes as this is a new feature addition that doesn't affect existing functionality
• No changes required to user MCP configurations

• Breaking change (fix or feature that would cause existing functionality to change)
• Documentation update

this is not following the mcp schema https://github.com/modelcontextprotocol/specification/blob/main/schema/2024-11-05/schema.json#L80

it should be something like

        return {
          content: [{ type: "text", text: JSON.stringify(comment, null, 2) }],
        };
