Makes sure that all static blocks have a distinct ID defined.

## Examples

The following examples contain code snippets that either fail or pass this check.

### ✗ Fail

In the following example, there are two static blocks using the same ID:



```liquid
{% content_for "block", type: "text", id: "static-block" %}
{% content_for "block", type: "text", id: "static-block" %}
```



### ✓ Pass

In the following example, the two static blocks have distinct IDs:



```liquid
{% content_for "block", type: "text", id: "static-block-1" %}
{% content_for "block", type: "text", id: "static-block-2" %}
```
