adding the ICONex connect specs somewhere in the devportal

I think is important to add a section, with a description and a link to the communication protocol for ICONex.

to explain it better, basically the devs of ICONex created an event based protocol to allow communication between a webpage / webapp and ICONex (installed as a plugin in the browser), this allows for the webapp to sign transactions without having to know the user private key, you basically make the user login with ICONex and the ICONex plugin signs the tx without exposing the private key.

to allow for compatibility the Hana team also implemented the same event based protocol to communicate with the Hana wallet, so at this point this event based protocol is a standard that we should continue to use with future wallets and with all the web apps.

because of this I believe is important to add a section maybe named "Communication protocol for ICON wallets" or something more descriptive, inside the article we can copy/paste the content of the link describing the protocol or improve it a little bit by explaining it more

I'm going to wait until the conclusions of the discussions surrounding the IIPs for wallet access so that the appropriate information can be added
