This commit fixes invalid prop spreading warnings in all the table rows
I could find through a quick search in the code base.
The issue is that you can't spread the "key" prop into a component. It
*must* be an explicit prop.
The process is the same everywhere:
1. Instead of spreading `row.getRowProps()` into the component, we
extract and split it: `const {key, ...rowProps} = row.getRowProps()`.
2. Do the same thing for cellProps.
