GraphQL field filtering is using the wrong field index

[gvkries]

Describe the bug

When filtering content items in GraphQL by indexed content fields, the field name and part are not considered. This issue arises when multiple fields of the same type are added to a content type, leading to incorrect items being returned. Specifically, querying one field may inadvertently include values from another field of the same type.

Orchard Core version

2.x and newer

To Reproduce

1. Enable indexing for content fields.
2. Create a content type with two fields of the same kind (e.g., two numeric fields).
3. Create content items with different values in each field.
4. Perform a GraphQL query for one of the fields.
5. Observe that the query results incorrectly include values from the other field.

Expected Behavior

The GraphQL query should only return items that match the specified field and part, without including values from other fields of the same type.
