Add support for filters in webhook registration

To support passing a filter to webhook registrations, the filter
parameter is needed.

Needs to update the shopify_api dependency to >= 14.7.0, which is the
first version of the api that includes the support to the filter
parameter.

+If you need to filter by webhook fields, you can register a webhook with a `filter` parameter. The documentation for Webhook filters can be found [here](https://shopify.dev/docs/apps/build/webhooks/customize/filters).
+
+```ruby
+ShopifyApp.configure do |config|
+  config.webhooks = [
+    {
+      topic: 'products/update',
+      path: 'api/webhooks/products_update',
+      filter: "variants.price:>=10.00",
+    },
+  ]
+end
+```
+
 If you'd rather implement your own controller then you'll want to use the [`ShopifyApp::WebhookVerification`](/lib/shopify_app/controller_concerns/webhook_verification.rb) module to verify your webhooks, example:
 
 ```ruby
