Fixed following issues related to auto-update:

1. Fixed the issue where auto-update was not working for macOS x64 arch machines as pgadmin4 zip file name has x86_64 in it.
2. Improved error handling in the /upgrade_check API by replacing the static “Failed to check for update” message for Windows users with a dynamic error message.
3. Fixed the CSS issue affecting the close icon in the warning notifier.
4. Removed trailing periods from helper texts and notifier messages in the app’s auto-update workflow. #9133
