Add ability to input values for license and creator for every chart

[vytisbulkevicius]

Description:

Schema.org @dataset is added to the chart if the Title and description are filled: https://vertis.d.pr/qdMpO5

Schema on the page - https://vertis.d.pr/QZQp4r

This works fine, however, when checking on Google structure data testing tool, there are warnings about adding two optional/recommended properties (license and creator):
https://vertis.d.pr/vbFu9u

There are many optional properties - https://developers.google.com/search/docs/data-types/dataset#dataset
However, warnings are thrown only for license and creator.

This doesn't break schema but as these are only 2 properties throwing warnings maybe we can add fields to the plugin's UI and allow users to input values for these 2 properties?

Alternatives:

An alternative is to use a filter and modify the string of Schema, for example to add license (to all charts):
add_filter( 'visualizer_schema', function( $schema, $chart_id ) {
			$schema = str_replace('
			}', ',
			  "license":"https://urlicense.com"
			}', $schema);

		return $schema;
	}, 10, 2 );

Or per chart -

add_filter( 'visualizer_schema', function( $schema, $chart_id ) {
if ($chart_id = 13) {
$schema = '{
"@context":"https://schema.org/",
"@type":"Dataset",
"name":"Title of your chart that will replace what is set in Visualizer",
"description":"Description of your chart that will replace description set in Chart settings",
"license":"https://creativecommons.org/publicdomain/zero/1.0/"
}';
}
return $schema;
}, 10, 2 );

For users that have many charts, this is not a very practical approach.

@vytisbulkevicius As per the requirement, we have added 2 new fields (Creator and License) in chart settings. Now the warnings are disspeared.

QA steps

1. You need to create a new chart or you need to edit the existing chart.
2. Go to the Settings tab from the right-hand side for the open chart.
3. Open/Expand General Settings from Settings tab.
4. Expand the Title & Description fields to enter values for the chart.
5. Expand additional new fields License & Creator fields and add the value to it.
6. Click to Create chart / Save chart for adding/updating value of the chart.

We have a question for the following chats.

1. Gauge
2. Timeline
3. Polar Area
4. Radar/Spider
5. Geo
6. Table

Is there any reason you haven't added the description field in settings for all the above charts?

We will not able to add (Creator and License) fields for all the above charts because the description field is required to validate chart schema.

To fix the above issue, we need to add a description field for all the charts.

@girishkrishaweb if the description field is required to validate it, we can add it.

Ok sure. Let me add it. @selul
