to generate a trusted root certificate, an intermediate certificate, and a server certificate.
We use `certificateAuthority(int)` to create certificates that can sign other certificates. The
int specifies how many intermediate certificates are allowed beneath it in the chain.

```java
HeldCertificate rootCertificate = new HeldCertificate.Builder()
    .certificateAuthority(1)

In beiden Fällen wird sie haben:

* Einen optionalen `q`-Query-Parameter, der ein `str` ist.
* Einen `skip`-Query-Parameter, der ein `int` ist, mit einem Defaultwert `0`.
* Einen `limit`-Query-Parameter, der ein `int` ist, mit einem Defaultwert `100`.

In beiden Fällen werden die Daten konvertiert, validiert, im OpenAPI-Schema dokumentiert, usw.
