meson: fix misspelled kwarg name

set10 doesn't have a `Description` kwarg, it does have a `description`
kwarg though.

This caused the conf variable to not have a description when it should
have one, and newer versions of Meson with better argument validation
error out with:

meson.build:58:5: ERROR: configuration_data.set10 got unknown keyword arguments "Description"
