Updated capitalization validation for utts

Hi Jason,

I updated the capitalization for the utterances column.

On a side note, although I can sync my local repository with your upstream repository, I'm having trouble pushing my local repository onto github afterwards. I keep getting a the following error:
error: The requested URL returned error: 403 Forbidden while accessing https://github.com/moniker001/ldp-valid.git/info/refs

fatal: HTTP request failed
