Conditional type safety for score

[A-Vamshi]

Fixed the TypeError from the issue #1629
Aggregated the score if it is an instance of list to average of the scores

Someone is attempting to deploy a commit to the Confident AI Team on Vercel.

A member of the Team first needs to authorize it.

@A-Vamshi actually i fixed it in here already: 1b52189#diff-cac10f0ffab564dfa6232eaf44643f86e3054ef8ba85187eea12261b2ddd07d6

the problem was the schema for some should be score: float instead of score: List[float] but there was a copy and paste error when building it initially :)

@penguine-ip ah gotcha, sorry I didn't check the schema, thanks!
