Add TypeScript code snippets to third-party tools documentation

[koverholt]

This PR adds TypeScript code examples alongside existing Python snippets for third-party tool integrations, which helps developers use these tools with ADK JS.

• Add TypeScript code examples to third-party MCP tools pages
• Add language support tags (Python/TypeScript) to all third-party tools pages
• Restructured code snippets to use nested tabs: outer tabs for language (Python/TypeScript), inner tabs for connection type (Local MCP Server/Remote MCP Server)
• Update Atlassian endpoint: /v1/sse → /v1/mcp
• All code samples tested with ADK JS 0.2.4 and the respective third-party tool

Marking this as blocked / do not merge because of a pending issue / PR in ADK JS that blocks a subset of these tools from working with the current version of ADK JS. This happens with MCP servers that return tools schemas without a specified type in some fields:

• MCPToolset error when MCP tool schema has property without type field adk-js#88
• Fix crash when MCP tool schemas contain empty types (items: {}) adk-js#75

Once a new version of ADK JS is released that includes that fix, this PR will be ready for review / merging.

ADK JS 0.2.5 has been released and I verified that it fixed the underlying issue.

So this PR is ready for review.
