[HarshMN2345]

What does this PR do?

This PR improves the user experience by enhancing the description text for encrypted string attributes in the collection attribute creation modal. The change splits a long sentence into two clear, separate sentences and improves the messaging around privacy compliance benefits.

Test Plan

1. Navigate to any project's database collection
2. Click "Create attribute" and select "String"
3. Scroll down to the "Encrypted" checkbox section
4. Verify the description text now shows two clear sentences:
   • "Protect attribute against data leaks for best privacy compliance."
   • "Encrypted attributes cannot be queried."
5. Confirm the text is more readable and better explains both benefits and limitations
