Xcode 15 introduced an [error](https://github.com/flutter/flutter/issues/132755) into Cocoapods when building macOS apps. 

When `pod lib lint` runs, it under the covers is building the app with `xcodebuild`, which is why this error occurs when linting.

A fix has been made in Cocoapods, but is not in an official release so we can't upgrade Cocoapods yet. This is to temporarily ignore lint failure due to that error.

Fixes https://github.com/flutter/flutter/issues/132980.

Tracking issue to upgrade Cocoapods when fix is in a release: https://github.com/flutter/flutter/issues/133584

Since Xcode 15 isn't in CI, I tested it in a one-off led test:
* [Pre-fix failure](https://chromium-swarm.appspot.com/task?id=6431f228ecf98e10)
* [Post-fix success](https://chromium-swarm.appspot.com/task?id=645ba7ebdab97210)
