fix(ios): Find .xcode.env in the debug symbols phase under SwiftPM

📜 Description

The Expo plugin "Upload Debug Symbols to Sentry" phase now uses $SRCROOT to find .xcode.env when PODFILE_DIR and PODS_ROOT are not set. The order is PODFILE_DIR, then PODS_ROOT/.., then SRCROOT. Thus CocoaPods projects do not change.

💡 Motivation and Context

After react-native spm add --deintegrate, the project has no CocoaPods, so PODS_ROOT is empty. The phase looked for /../.xcode.env and did not find NODE_BINARY. When Xcode starts from the Dock, node is not on PATH, so the phase failed. The SwiftPM build phases of React Native 0.87 use $SRCROOT/.xcode.env for the same reason.

Related to #5780.

💚 How did you test it?

Added two shell tests in modifyXcodeProject.test.ts. One runs the phase with only SRCROOT set and no node on PATH. This test failed before the fix. The other test makes sure that PODS_ROOT has priority over SRCROOT.
