support kebab casing in vite_asset template tag

[kierangillblueberry]

Attributes can be set on the entry script tag by using the following syntax:

{% vite_asset '<path to your asset>' foo="bar" hello="world" %}

However, this does not allow for kebab-cased attributes. We are using a framework that requires we set the data attribute data-turbo-track="reload" on the entry <script />.

Since kebab-cased attributes cannot be supported via kwargs, vite_asset has been updated to support JSON encoded attributes:

from django.utils.safestring import SafeString

def your_view(request):
  json_encoded_attributes = json.dumps({
    "some-item": "3",
    "some-other-item": "value",
  })

  render(request, template, context={ "json_encoded_attributes": SafeString(json_encoded_attributes) })

{% vite_asset '<path to your asset>' json_encoded_attributes=json_encoded_attributes %}

Closes #127

This is a great feature idea! I made a PR that expands on it -- we should convert underscore_cased attributes to kebab-case automatically.

See: #131
