Funktion key from config gets overwritten by function key in url

[Derich367]

Describe the issue
When requesting swagger ui with query parameter "code", the configured function key from parameter "OpenApi__ApiKey" is not used to request open api file. Instead the code from url is used.

In production environment, you normally use function specific keys, so you will need a diferrent key to access swagger ui and request swagger.json. But when requesting swagger ui with a key inside of the query, the same key is used for requesting swagger.json and not the configured key from function parameters.

To Reproduce
Define parameters in local.settings.json:
{ "OpenApi__ApiKey": "functionKey", "OpenApi__AuthLevel__Document":"Function", "OpenApi__AuthLevel__UI":"Function" }

Request Swagger Ui with http://localhost:7071/api/swagger/ui#/?code=otherFunctionKey

The url for swagger.josn is now http://localhost:7071/api/swagger.json?code=otherFunctionKey

Expected behavior
The url for swagger.json should be http://localhost:7071/api/swagger.json?code=functionKey
