admin_oidc_url is documented to not be dynamic when in fact it is

The admin_oidc_url is documented to not be dynamic which means it cannot be modified at runtime. The setting is dynamic and it can be modified at runtime but it only gets updated whenever maxctrl reload tls is executed or if the admin_ssl_cert and admin_ssl_key settings are modified.

The documentation should be corrected to state that the setting is dynamic and the behavior of the settings should be made consistent so that only a modification of admin_oidc_url is needed to trigger the reloading of it.
