inso lint cannot run against custom spectral ruleset with "excepts" including paths

### Expected Behavior

It lints and respects the `excepts` section in the custom ruleset.

### Actual Behavior

It fails with:

> FATAL Document must have some source assigned. If you use Spectral programmatically make sure to pass the source to Document

### Reproduction Steps

By copyting this spectral ruleset file in the same folder as the openapi.yaml file, you can produce the error:

```yaml
extends: spectral:oas

except:
"./openapi.yaml#/paths/~1v1~1cars/post/responses/202/content/application~1json/examples":
- oas3-valid-media-example

```
