Unfortunately that terminal requires an insider's version of Windows to run.
Enabling insiders means MS will track a bunch of data about you besides anonymous metrics and you can't opt out of it because insiders requests that info.
WSL v2 and / or that terminal sounds good but it may not be until Oct 2019 or Apr 2020 before the stable Windows channel sees it. They tend to release 2 major updates a year and if WSL v2 is only being released in June 2019 for insiders it's quite the push to have it ready by Oct 2019 for stable.

As much as Microsoft tries to change it still remains the same...
