Update test_android_template to use npm pack

I'm updating the `test_android_template` CI step to use npm pack instead of sed-ing the RN version to `file:..`.
This should be more robust and will allow to install transitive deps automatically, without having to deal with separate installation steps.

This also fixes the broken CI for Android

Changelog:
[Internal] [Changed] - Update `test_android_template` to use `npm pack`
