Fix up spreadsheets for workshop registrant info

[Aariq]

Currently there are two separate google sheets documents corresponding to two different zoom reports:

• https://docs.google.com/spreadsheets/d/15E5JDNiVr9aCWYE4iFSirvwzdllLtWEEZAwYi3_TScE/
• https://docs.google.com/spreadsheets/d/1SU8Wtx7Ku1IMv8DOAU-37E12-AZP0CjnRy1vPSkmNGQ/

For one of them, the column headers don't match the CSV exported from Zoom, which sucks for copy paste. Do we need both? Should they be two tabs in the same sheet? What will we do with this info?

My thoughts are that if/when we do anything with this info, we can do it programmatically (i.e. with spreadsheet formulae on a separate tab or with R), so let's make this step as simple as possible. E.g. drop each .csv in a Google Drive folder or copy and paste verbatim (all columns) into two different tabs of a Google Sheets doc.
