GraphQL filter error in Insights panel for M2A relationship

### Describe the Bug

In the insights panel, I was using the List panel type to get a list of articles that contain a M2A section that has a wysiwyg field that contains a particular word. When setting up a filter for that M2A section, the filter builds this raw string:
```
{
"_and": [
{
"sections": {
"item:body": {
"content": {
"_contains": "certainword"
}
}
}
}
]
}
```

However graphQL does not like "item:body" because of the colon. I was able to resolve the issue by manually changing the raw string to "item__body" with two underscores. But I'm thinking that this should happen with the regular editor tools without having to edit the raw string.

### To Reproduce

1. Create an Insights List Panel item. Use a collection with a M2A collection.
2. Try to filter on a field within that relational field.
