Renewal of expired certificate

**Describe your question/**
The default authentik Self-signed Certificate has expired and the one I've created to use with ldap will expire soon. The [documentation](https://goauthentik.io/docs/core/certificates) doesn't mention what the correct way to renew this is. Should these be deleted and then be replaced by newly generated ones or is there a way to renew these?
