chore(ci): use latest jetpack image for l4t (#7926)

This image is for HW prior Jetpack 7. Jetpack 7 broke compatibility with
older devices (which are still in use) such as AGX Orin or Jetsons.

While we do have l4t-cuda-13 images with sbsa support for new Nvidia
devices (Thor, DGX, etc). For older HW we are forced to keep old images
around as 24.04 does not seem to be supported.
