Reconsider traefik config options set for HTTPS

[peb-adr]

tls:
  certificates:
    - certFile: ${HTTPS_CERT_FILE}
      keyFile: ${HTTPS_KEY_FILE}
      stores:
        - default
  stores:
    default:
      defaultCertificate:
        certFile: ${HTTPS_CERT_FILE}
        keyFile: ${HTTPS_KEY_FILE}

As far as I understand, this set's all possible (SNI matched, default, more?) certificates to the locally provided one.
We might to be more specific here about when to use which cert. Time and observation will have to tell though.
