This PR fixes #297 and sets the callback_group of the publisher options for the voxel_grid publisher. Before the callback_group for the subscriber options was set twice.
Tested on humble with no perceptible changes, everything seems working fine. I don't know exactly the consequences of not setting the callback_group (e.g. get_subscription_count() was also working even with the default options without setting it), but it makes more sense to fix this typo now and prevent future problems.
