Updates to icees-kg EPC and predicates

[karafecho]

This issue is to follow up on the following updates to icees-kg, marked for completion after the September release.

1. Delete current biolink:supporting_data_source attribute block from edges
2. Add biolink:has_supporting_study_result attribute to analysis blocks, following COHD’s example:

• And on each biolink:has_supporting_study_result attribute on each edge (multiple per edge):
  "value_url": "https://github.com/NCATSTranslator/Translator-All/wiki/COHD-KP"

• See: How can we harmonize supporting data sources?  biolink/biolink-model#1352

3. Add back RWE edge, but keep the correlated_with, positively_correlated_with, and negatively_correlated_with edges.

@maximusunc : As long as we're planning to change the Biolink type to biolink:has_supporting_study_result, can we change the title of our wiki page from https://github.com/NCATSTranslator/Translator-All/wiki/Exposures-Provider-ICEES to https://github.com/NCATSTranslator/Translator-All/wiki/ICEES? I can change the title itself and create a ticket to change the URL in the infores catalog, but you will need to change the URL on icees-kg edges. Does this seem reasonable?

[maximusunc]

Yep, that's fine!

Decision, 10.18.2023:

1. Max will change biolink:supporting_data_source to biolink:has_supporting_study_result.
2. Max will change the URL from https://github.com/NCATSTranslator/Translator-All/wiki/Exposures-Provider-ICEES to https://github.com/NCATSTranslator/Translator-All/wiki/ICEES.
3. Kara will then change title of wiki page.

Hold off on listing multiple URLs for supporting study results until after a decision is made regarding whether TRAPI will support the ability to include lists as supporting study results.

Hold off on adding knowledge level (KL) type to edges until after a decision is made regarding whether / when the EPC WG will move forward with proper approach for exposing KL type, which is to have KPs provide this information as part of the TRAPI message.
