35182	Add support for additional HTML attributes to json_script template tag	LB (Ben Johnston)	nobody	"The `json_script` template filter is useful for bootstrapping server side data into some client-side widgets or JS driven config.

However, in it's current state only a HTML id attribute is supported which means that if you want to leverage low-JS libraries such as Stimulus, HTMX or Alpine.js to 'listen' for the element you have to add an extra layer for finding elements by an id.

Additionally, it makes it difficult to modify other HTML attributes such as `nonce`.

While the type being JSON has an intentionally smaller use case than external scripts it would still be very useful to be able to add other attributes.

Example usage

    {{ value|json_script:""hello-data""@""data-controller='my-controller'"" }}

Would output

    <script id=""hello-data"" type=""application/json"" data-controller='my-controller'>{""hello"": ""world""}</script>

I'm not sure on the best separator for the attributes or if a string or some other value would be better. It would also need to support non-id usage.
