Removed SDL_HINT_RENDER_OPENGL_SHADERS

Shaders are always used if they are available.

@@ -710,6 +710,7 @@ The following hints have been removed:
 * SDL_HINT_MOUSE_RELATIVE_SCALING - mouse coordinates are no longer automatically scaled by the SDL renderer
 * SDL_HINT_RENDER_BATCHING - Render batching is always enabled, apps should call SDL_FlushRenderer() before calling into a lower-level graphics API.
 * SDL_HINT_RENDER_LOGICAL_SIZE_MODE - the logical size mode is explicitly set with SDL_SetRenderLogicalPresentation()
+* SDL_HINT_RENDER_OPENGL_SHADERS - shaders are always used if they are available
 * SDL_HINT_THREAD_STACK_SIZE - the stack size can be specified using SDL_CreateThreadWithStackSize()
 * SDL_HINT_VIDEO_FOREIGN_WINDOW_OPENGL - replaced with the "opengl" property in SDL_CreateWindowWithProperties()
 * SDL_HINT_VIDEO_FOREIGN_WINDOW_VULKAN - replaced with the "vulkan" property in SDL_CreateWindowWithProperties()
