I @Cesar_Niemeyer, welcome to the forum!
@drwtsn32 is correct that you can just download 22.214.171.124 and install it “over” 126.96.36.199 if you’d like.
However, if you want to use the auto updater then since the 188.8.131.52 that you’re on is on the “experimental” channel and the 184.108.40.206 you want to get to is on the “beta” channel, you’ll need to go to the main menu Settings page and change the Update channel to “beta” then click the “OK” button.
After that you can wait a bit for an update check to happen automatically or you can go to the “About” -> “General” page and click the “Check for updates now” link.
Note that I updated the title of this topic to make it clear that the question is about updating from one channel (experimental) to another (beta).
