In d0478c41f4 ("libcamera: Rename "shutter speed" to "exposure time"")
the tuning file entry "shutter" was renamed to "exposure-time". As the
tuning files use camel cased key names, change "exposure-time" to
"exposureTime" for consistency. It doesn't break our users setups as
there are no tuning files using that entry in the wild (at least
officially).
