Bug 1797050 - Part 5 - Use `browser_specific_settings` instead of `applications` in android test extensions. r=owlish

We want to encourage extension developers to use `browser_specific_settings` instead of `applications`,
which will be unsupported in Manifest Version 3+. This patch makes sure test extensions won't cause any
issues in the future.
