Revise 10 minutes notebook. (#10738)

Follow-up from #10685 to fix deprecation warnings in the 10 minute notebook.

Fixes: #10613
Changes:
- Fixed deprecation warning for `Series.applymap` ➡️  `Series.apply`
- Removed two cells demonstrating `Series.append`. This has also been removed from the Pandas 10 minute notebook because the feature is deprecated.
- Refactored ORC file path logic to be a bit simpler
