Merge remote-tracking branch 'origin/NR_SA_Tutorials' into integration_2025_w20 (!3422)

Tutorials: updates for NR SA Tutorials

- Update links for the latest Ubuntu 24.04.2 LTS iso file
- Update docker install to the latest instructions on the official
  website
- Update UHD to v4.8.0.0
- Add support for 'default'/"empty" DNN to CN5G configuration file
  * Add support for 'default' DNN to CN5G configuration file (that
    will also be used when DNN is not available, "empty" DNN). This
    configuration will allow most of the COTS UE to get PDUSession
    without any APN configuration made by the user
  * The 'default'/"empty" DNN configuration support was added in
    oai/cn5g/oai-cn5g-amf!343
