iOS template (0.84) unintentionally drops iPhone landscape support in Info.plist (after #183)

Description

As part of the work to support iPad window resizing (#183), the iOS community template shipped with RN 0.84 now lists only UIInterfaceOrientationPortrait under UISupportedInterfaceOrientations (iPhone). This removes iPhone landscape rotation for apps created from the current template, which has been the default behaviour for many years.

In the PR description for #183, the stated goal is to enable window resizing on iPad by listing all 4 orientations under UISupportedInterfaceOrientations~ipad. It doesn’t appear to intend changing iPhone behaviour. 

Current template behaviour (0.84)

In template/ios/HelloWorld/Info.plist, iPhone supported orientations are effectively portrait-only, whilst iPad has all four orientations. 

Expected behaviour

The template should keep the historical default for iPhone (portrait + both landscapes), whilst retaining the iPad-specific orientations needed for window resizing.

Impact

New iPhone apps created with @react-native-community/cli + the 0.84 template won’t rotate to landscape without manual plist changes.

Steps to reproduce

1.	npx @react-native-community/cli init AwesomeProject (current/0.84 template)
2.	Run on an iPhone simulator/device
3.	Rotate device → app remains portrait-only

No response

Start in template/ios/HelloWorld/Info.plist and inspect UISupportedInterfaceOrientations for iPhone and iPad. Reproduce with the 0.84.0 template using the listed CLI initialization steps, then verify that iPhone supports portrait and both landscape orientations while iPad retains all four.
