Fix iOS CI (#3228)

# Objective

- With #3109 I broke iOS CI: https://github.com/bevyengine/bevy/runs/4374891646?check_suite_focus=true

## Solution

- Fix indentation in makefile
- Adds scheme that is now needed

With this, `make install` works on my m1 Mac but still fails on my intel Mac unless I run something like `make install; cargo build --target x86_64-apple-ios; make install; cargo build --target x86_64-apple-ios; make install`. It seems something is off when executing cargo through `xcodebuild` on my setup but not sure what. So this PR will probably not fix iOS CI 😞
