Fixes run samples scripts for iOS and Android

[antonis]

📢 Type of change

• Bugfix
• New feature
• Enhancement
• Refactoring

📜 Description

This changes the run-ios and run-android scripts to use sequential commands instead of run-s

💡 Motivation and Context

I've run into the following error while trying to run the samples on v6

$ yarn run-ios
ERROR: Task not found: "cd", samples/react-native", yarn", react-native"
$ yarn run-android
ERROR: Task not found: "cd", samples/react-native", yarn", react-native"

💚 How did you test it?

Run the following commands from sentry-react-native project root:

yarn run-ios
yarn run-android

📝 Checklist

• I reviewed submitted code
• I added tests to verify changes
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled
• All tests passing
• No breaking changes
