Update ESLint config to restrict react native Picker import

[puneetlath]

We recently updated our ESLint config to restrict importing Text, TextInput, and Button from React Native (Expensify/eslint-config-expensify#38). We should also include Picker, which is a deprecated component, since that is also a component that we shadow. More context here: https://expensify.slack.com/archives/C01GTK53T8Q/p1639149638008700
