Potential spelling errors in Cater Waiter #4319

There were some spelling corrections made in this PR in relation to Cater Waiter which I found were copy and pasted from the Python version.

They don't seem to be of any functional importance, but, if you're interested, here are the relevant lines in the Python code:

• 'Bannana Punch' -> Banana Punch
• ';ime juice' -> 'lime juice'
• 'Bannana Punch' -> 'Banana Punch'

The Bannana error appears internally consistent (since it appears in both all_drinks and drink_names), and while ;ime isn't, I assume it's not tested.
