[Tracker] Remove CUDA version from Notebook image(s) version names

[harshad16]

After the work done to support multiple image versions for each OOTB Notebook image, we've begun showing image version "names" to the end user. RHODS-7908 aimed to streamline the naming convention into 2 for the 1.26 release (20XX.1 and 1.2) with the goal of moving to a single naming convention in the next OOTB update (i.e. 20XX.1, 20XX.2).
However, two Notebook images (CUDA and Tensorflow) still show a different version name, which includes the CUDA version. My suggestion is to put the CUDA version in the "description"/"subtitle" of the image itself rather than the version name in order to achieve the single naming convention that was agreed upon.

Issue: RHODS 8215
