 @descr:
 This config defines how baselines are handled and displayed in the Gantt chart. It can be set as an object to customize the display or as a boolean to enable or disable the feature. The object configuration contains the following properties:
 
-- **datastore** (*string*) - the name of the datastore used for storing baseline entries. For related functionality, see the `getDatastore` method.
-- **render_mode** (*boolean | string*) - determines how baselines are displayed:
-  - `false` - baselines are not shown.
-  - `"taskRow"` - baselines are displayed in the same row with the task bar.
-  - `"separateRow"` - baselines are shown in a separate subrow, expanding the task row height.
-  - `"individualRow"` - each baseline is displayed in its own subrow beneath the task.
-- **dataprocessor_baselines** (*boolean*) - specifies whether baseline updates trigger the DataProcessor as individual entries.
-- **row_height** (*number*) - defines the height of the subrow for baselines, applicable only when `render_mode` is set to `"separateRow"` or `"individualRow"`.
-- **bar_height** (*number*) - sets the height of the baseline bar.
