Fix: Ensure entity_or_relation_name is a string in _handle_entity_relation_summary

[SaujanyaV]

Description

I encountered an issue where the function _handle_entity_relation_summary raised the following error:

Argument 'entity_or_relation_name' has incorrect type (expected str, got tuple)

This error occurred because the function was being called with a tuple (src_id, tgt_id) instead of a string. To resolve this issue, I made the following changes:

Converted the Tuple to a Formatted String

Replaced the call to _handle_entity_relation_summary with:

description = await _handle_entity_relation_summary(
    f"({src_id}, {tgt_id})", description, global_config
)

This ensures that the entity_or_relation_name argument is always passed as a string.

Maintained Consistency

Updated the code to use formatted strings for better readability and alignment with the function's expectations.

Steps to Reproduce the Issue

1. Use the _merge_edges_then_upsert function with a graph edge where the tuple (src_id, tgt_id) is passed to _handle_entity_relation_summary.
2. Observe the type mismatch error when the function is executed.

---

Solution

Ensure entity_or_relation_name is a string by using a formatted string f"({src_id}, {tgt_id})" instead of the tuple.
