You can’t. Even when Firefox with uBO is your default browser and any other app just uses Firefox as the built-in browser, Google News will resort to Chrome.
For me (on Firefox non-beta) it just opens the in-app browser and shoves ads down my throat. I just checked it, Chrome is disabled and cannot be uninstalled on my phone.
When I have a page opened in the Google News App, I can tap the menu and select to open the web page from there. Then it gets opened in Firefox.
I recommend [URLCheck][1] — it intercepts the default browser and allows both modifying the opened URL (to remove tracking) and forcefully preventing the embedded browser (the bottom-left button).

Workaroud: Open the website in Firefox instead of using the app - https://news.google.com/
It will open Firefox or whatever your default browser is if you delete chrome or freeze it.
It won’t open the usual webpage though, it will open and create a new tab in the browser, at least that is the behavior that I face with Firefox Beta.
