bazel: update rules_apple (#2346)

To pull in bazelbuild/rules_apple#1488, which should fix our CocoaPods integration and allow us to re-add it.

Risk Level: Medium for iOS users who use the xcframework, low for everyone else
Testing: There's a recent CI job that validates SwiftPM integration that acts as a good integration test for this
Docs Changes: None for now, this isn't really a user-facing change, as Xcode/SwiftPM handles both the old and new xcframework format/layout transparently
Release Notes: None for now, this isn't really a user-facing change
