fix(jans-config-api): attribute `createdAt` Agama deployments type varitaion between `list` and `get`

[moabu]

When querying the list API for Agama deployments, the attribute createdAt is of type string (e.g. '2023-05-16T09:04:24'), whereas when using the get API, the attribute is of type number (i.e. timestamp). This currently breaks JSON unmarshalling.

that's weird, I fixed that a couple of weeks ago, will revisit

I confirmed it's working fine @moabu :

$ curl -i -k -H 'Authorization: Bearer moabu' -G https://acme.co/jans-config-api/api/v1/agama-deployment

This is a today install of Jans server (online installer). I think you are using old binaries. Actually the /list prefix was removed some time ago, just use /agama-deployment
