Refactor WebSocket URL construction to prioritize X-Forwarded-Proto header

[mahata]

This pull request refines the logic for constructing WebSocket URLs in the hono/routes/index.tsx file and updates the corresponding test cases in hono/routes/index.test.tsx. The changes ensure that the X-Forwarded-Proto header is prioritized when determining the protocol, improving support for proxied HTTPS requests.

Pull Request Overview

This pull request refactors the WebSocket URL construction logic to prioritize the X-Forwarded-Proto header when determining the protocol for WebSocket connections. This improvement enhances support for applications running behind reverse proxies that handle HTTPS termination.

• Changed protocol detection from URL-based to header-based approach using X-Forwarded-Proto
• Updated test case to verify the new header-based protocol detection logic

• The test coverage is incomplete. The original test for direct HTTPS requests was removed, but there should be tests covering: 1) direct HTTPS requests without proxy headers, 2) X-Forwarded-Proto with non-https values, and 3) missing X-Forwarded-Proto header scenarios.
