Update auth config json test

[adam-cattermole]

One of the integration tests is failing https://github.com/Kuadrant/kuadrant-operator/actions/runs/10625397804/job/29455286217#step:7:122

I think this is related to the changes to store as v1beta2. I can't quite pinpoint exactly why but before the credentials field had the authorizationHeader present (even though it's omitempty), whereas now it does not - I'm guessing some logic in the webhook was incorrect and was creating an empty Prefixed so the pointer was not null - I've updated all 3 occurrences in the json string.

Before:

"credentials":{"authorizationHeader":{}}

After:

"credentials":{}

I believe the behaviour now looks correct but looking to @guicassolato or @alexsnaps to confirm.

My only guess is something to do with this kubebuilder validation was making Credentials_In not empty which meant that building the credentials in the original webhook to convert from v1beta1 -> v1beta2 set authorizationHeader to an empty Prefixed instead of null?

[guicassolato]

IDK why exactly we were getting {"authorizationHeader":{}} before, but it could be due to a difference in the procedure between mashalling the content before versus just reading it from storage now.

Either way, the fix seems correct to me.

Thanks, @adam-cattermole!
