fix(docker): fixes when generating the templates for gNB conf files

* The '0x' format was forgetting that an hexadecimal value can have a-f chars
  * If someone wants to use a dedicated NSSAI_SD value, it is possible now
  * For experimental purpose in cluster, SDR addresses can be provided for one config
    - could be expended later on other conf files
