Updated custom outputType options for researchOutputTable to include "description"/"comment"

[jupiter007]

Currently, when a user saves a custom output type in Research output table question form, it is saved in the question's JSON like:

{
			"meta": {
				"schemaVersion": "1.0",
				"labelTranslationKey": "researchOutput.outputType"
			},
			"content": {
				"meta": {
					"schemaVersion": "1.0"
				},
				"type": "selectBox",
				"options": [
					{
						"label": "Audiovisual",
						"value": "audiovisual",
						"selected": false
					},
					{
						"label": "Collection",
						"value": "collection",
						"selected": false
					},
					{
						"label": "Data paper",
						"value": "data-paper",
						"selected": false
					},
					{
						"label": "Dataset",
						"value": "dataset",
						"selected": false
					},
					{
						"label": "Event",
						"value": "event",
						"selected": false
					},
					{
						"label": "Image",
						"value": "image",
						"selected": false
					},
					{
						"label": "Interactive resource",
						"value": "interactive-resource",
						"selected": false
					},
					{
						"label": "Model",
						"value": "model",
						"selected": false
					},
					{
						"label": "Other",
						"value": "other",
						"selected": false
					},
					{
						"label": "Physical object",
						"value": "physical-object",
						"selected": false
					},
					{
						"label": "Service",
						"value": "service",
						"selected": false
					},
					{
						"label": "Software",
						"value": "software",
						"selected": false
					},
					{
						"label": "Sound",
						"value": "sound",
						"selected": false
					},
					{
						"label": "Text",
						"value": "text",
						"selected": false
					},
					{
						"label": "Workflow",
						"value": "workflow",
						"selected": false
					},
					{
						"label": "My output type",
						"value": "my-output-type",
						"selected": false
					}
				],
				"attributes": {
					"help": "",
					"multiple": false,
					"labelTranslationKey": "researchOutput.outputType.heading"
				}
			},
			"enabled": true,
			"heading": "Output Type",
			"required": true
		},

However, when they add a custom output type, they should be able to add a "description" field that will be used with the "info icon" tooltip, so that users can click on the "info icon" to get more details about that specific output type. However, there is currently no place to store that in the schema.

We need to add description to the schema. It should be optional so that it is backwards compatible We can replace "Selected" with "Description" because we don't need selected in this view.

This is to support when people add custom variables to the Output Types with descriptions, where we have the user enter it for their own variables and we take a snapshot of the description from the default ones.

Will need a FE ticket after this work is done to add the descriptions from this table to the list upon editing the question when it calls the BE.

We should also create a FE ticket to warn the user if they switch back to the default list, that their customizations will be deleted and not recovered.
