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
