Correct name of tunnel.pyjam.as

Hello! 

Thank you so much for adding our project https://tunnel.pyjam.as to your list!

This is just a small correction, but `pyjam.as` is the name of our organization, and the project name is `tunnel.pyjam.as`

I also added a link to our source code

Thank you again! :)

Users are encouraged to use it for SSH exposure only, to preserve end-to-end encryption. No public ports, only in-SSH connectivity. Run `ssh ssh-j.com` and it will display usage information.
 * [frp](https://github.com/fatedier/frp) [![frp github stars badge](https://img.shields.io/github/stars/fatedier/frp?style=flat)](https://github.com/fatedier/frp/stargazers) - Comprehensive open alternative to ngrok. Supports UDP, and has a P2P mode. I believe it uses a custom TCP protocol for multiplexing, which can either run over a single TCP connection or a connection pool.
 * [ngrok 1.0](https://github.com/inconshreveable/ngrok) [![ngrok 1.0 github stars badge](https://img.shields.io/github/stars/inconshreveable/ngrok?style=flat)](https://github.com/inconshreveable/ngrok/stargazers) - Original version of ngrok. No longer developed in favor of the commercial 2.0 version.
