feat: Add Golang server implementation (arcaela/socket.io-client-go)

This PR adds `arcaela/socket.io-client-go` as an alternative Golang server implementation to the official documentation.

## Context

The currently listed Golang server repository (`googollee/go-socket.io`) has been archived and is no longer actively maintained. While there are existing open PRs (socketio#487, socketio#491) proposing URL replacements, this contribution introduces a fully independent and actively maintained implementation rather than simply updating the existing link.

## About this implementation

- **Full protocol compliance**: Implements the Socket.IO protocol according to the official specification, including Engine.IO v4 and Socket.IO v5 support.
- **Comprehensive test coverage**: The codebase has been thoroughly tested to ensure reliability and protocol adherence.
- **Standards-compliant documentation**: Official documentation follows Socket.IO's established conventions and standards.
- **Active maintenance**: The repository is actively maintained and open to community contributions.
