Upgrade from C130 -> C131 on Android ARM x64 via 1.73.x - Nightly (Checking C131)

[LaurenWags]

As per process, QA runs through the following cases to ensure that the major chromium bump that's about to get merged into master doesn't regress the Nightly channel. Once the major chromium bump is merged into master, QA will run through a full manual pass on Windows & Android.

Startup & Components

• Verify that Brave is only contacting *.brave.com endpoints on first launch using either Charles Proxy, Fiddler, Wireshark or LittleSnitch (or a similar application)
  • Verify that opening a NTP doesn't trigger any outbound connections related to widgets without user interaction
• Restart the browser, load brave://components, wait for 8 mins and verify that no component shows any errors

Note: Always double check brave://components to make sure there's no errors/missing version numbers. We basically want to make sure that components are working as they regressed in C98 when we first merged into master.
