🔧 Kernel User script: joyvan -> analyticalplatform in kernel.json

[Gary-H9]

Raised in relation to this issue.

Summary

This PR adds a script to automate the replacement of the string "jovyan" with "analyticalplatform" in any kernel.json files located under the base directory /home/jovyan/.local/share/jupyter/kernels.

Script Explanation

The script performs the following actions:

1. Defines BASE_DIR: Specifies the base directory where Jupyter kernel files are located (/home/jovyan/.local/share/jupyter/kernels).
2. Finds All kernel.json Files: Uses the find command to locate all kernel.json files within BASE_DIR and its subdirectories. The find command searches recursively, so it will locate any kernel.json files in all directories under BASE_DIR (e.g., /home/jovyan/.local/share/jupyter/kernels/dir1, /home/jovyan/.local/share/jupyter/kernels/dir2, etc.).
3. Replaces String in kernel.json Files: For each kernel.json file found, the sed command replaces occurrences of "jovyan" with "analyticalplatform".

Example Directory Structure

The script will successfully modify kernel.json files in a directory structure like this:
/home/jovyan/.local/share/jupyter/kernels/

├── dir1/ 
│
└── kernel.json 
├── dir2/
