[UDF] creating external library example is incorrect based on new design

https://docs-staging.couchbase.com/server/7.0/n1ql/n1ql-language-reference/createfunction.html#context

On this page the screenshotted example is now wrong. Basically the way to create external library functions was changed, I am not sure if this needs to be updated in other places besides this one but this is where I noticed it, the correct way to create functions now is as follows. I'd imagine the creating library documentation will need an overhaul if it hasn't been changed already

curl -X POST http://172.23.123.66:8093/evaluator/v1/libraries/math -u Administrator:password -H 'content-type: application/json' -d 'function adder(a, b)

function multiplier(a, b)

'

The endpoint and syntax have both changed
