fix: Update openinference-vercel semantic convention mapping for output

[luke-moehlenbrock]

Suggested change

	result: "response",
	response: "response",

[Parker-Stafford]

https://github.com/Arize-ai/openinference/blob/main/js/packages/openinference-vercel/src/AISemanticConventions.ts#L53-L60
to response as well and key off AIPrefixes.response

and these
https://github.com/Arize-ai/openinference/blob/main/js/packages/openinference-vercel/src/utils.ts#L460-L471

[luke-moehlenbrock]

Thanks for the suggestions @Parker-Stafford and @mikeldking! I went through and changed result to response throughout the package
