Add Script to Migrate Emails from profiles to users collection

[kiminkim724]

Summary

This script migrates email addresses from the profiles collection to the users collection in Firestore.

• For each profile document with an email:
  • Checks if the corresponding user document already has an email.
    • If the user document does not have an email:
      • Copies the email from profiles to users.
      • Deletes the email field from the profile document.
    • If the emails are the same:
      • Deletes the email field from the profile document.
    • If the emails are different:
      • Logs an error with the user ID and both email values, then skips updating.

Checklist

• On the frontend, I've made my strings translate-able.
• If I've added shared components, I've added a storybook story.
• I've made pages responsive and look good on mobile.
• If I've added new Firestore queries, I've added any new required indexes to firestore.indexes.json (Please do not only create indexes through the Firebase Web UI, even though the error messages may reccommend it - indexes created this way may be obliterated by subsequent deploys)
