This enhancement exposes any WMTS "time" dimensions for use in the temporal framework, including allowing these layers to be animated and controlled via the temporal controller.
When we do detect a time dimension on a WMTS layer, we no longer expose this in the same way as other non-time dimensions. The browser panel does not show the dimension values, and adding the layer via Data Source Manager no longer prompts the user to pick from the available time values. Instead, these layers are indicated with a new "time capable raster layer" icon, and are added to a project without the user specifying a time value.
Just like a WMS(T) layer, when a time-dimension enabled WMTS layer is added to the project, it will default to the "automatic" temporal mode, meaning that the layer will follow the temporal controller's current time range by default. A user can then opt to show a specific static time value for the layer through the layer's Temporal properties page, by unchecking "Dynamic Temporal Control" and picking a specific available time range from the "Predefined date" option.
This should unify the user experience so that the usage of WMTS time-enabled layers is essentially identical to the usage of WMS(T) layers.
