Align the capitalization of the term "Bluetooth Mesh" to Bluetooth mesh" in the documentation. This is done to to match the new updated naming convention done in Bluetooth SIG. In the upcoming spec versions, it its used "Bluetooth mesh" with the lower case convention. Signed-off-by: Ingar Kulbrandstad <ingar.kulbrandstad@nordicsemi.no>
