CODE_SIGN_STYLE should default to "Automatic" for iOS projects.

Ahoy! Found this while debugging my workflow.

XCode projects that that don't specify CODE_SIGN_STYLE use Automatic code signing per iOS defaults.
Steps like xcode_archive end up setting up Manual code signing for these projects as a result, leading to unexpected code signing issues later in the build.

Not sure if other Apple platforms have different defaults for CODE_SIGN_STYLE.

Explicitly setting CODE_SIGN_STYLE is a workaround.

Ahoy @jfrndz - As you mentioned, the code only falls back to manual code sign style if CODE_SIGN_STYLE is not defined in the project settings. Can you help us understand how this can happen in a project (that there is no code sign style defined)?

Side note: if you want to avoid unexpected code signing issues, we recommend disabling the automatic_code_signing input entirely - with this setting, the step won't modify any code signing setting in the project nor install any certificates and profiles.
