For the sake of clarity might we say:

# Gather the dashboard URL (provided by the RayCluster creator)

"ray_dashboard = \"<Ray-Dashboard-Route>\"\n",
"\n",
"# Setup Authentication Configuration \n",
"\n",
"header = {\n",
" 'Authorization': f'Bearer {\"<auth-token>\"}'\n",

Maybe something like this would be clearer:

auth_token = "XXXX" # Your OpenShift authentication token

header = {
    'Authorization': f'Bearer {auth_token}'
}

"}\n",
"\n",
"#Initialize the RayJobClient\n",
"client = RayJobClient(address=ray_dashboard, headers=header, verify=True)"
]
