Ts/2509 task update entity similarity api

[Tom-Szendrey]

Description

This updates the API to have the newly named similarity instead of distance
Also this updates minor formatting now that datasets are more consistent

Notes

I still need to make this only return the best result for each aka 1:1 mapping.
I will do that next PR.

Testing:

Add some concepts to a dataset and a model
hit the automap
check the logs to make sure it makes sense
check results to make sure it makes sense
