Video Badge 3: mistake in code

[drpawelo]

raided by Yue T from Software Dev for Health and Social Care: in the badge 3 video code example at 14m:40s is badly copy-pasted (Thursday appears in many places too many)

actually, just the first line was wrong. Fixed in slides.

 if day == "Wednesday":
    message = "sorry, we're closed on Wednesdays"
