Fixed CascadeChoiceParameter with RADIO choice type both in classic UI and new job page

[Eyepatch5263]

Fixed the issue #929 cascadeChoiceParameter with radio choice type bug which was occurring when we are doing a freeStyle job with choice and active choice reactive parameter.

Testing done

Created a Freestyle Job with name: test-groovy-script-radio-bug-repro
added first parameter as choice type with
Name: ENVIRONMENT
Choices:
development
staging
production
and second Parameter of type Active Choices Reactive Parameter with
Name: CONFIG_FILE
Choice Type: Radio Buttons
Referenced parameters: ENVIRONMENT and also add a Groovy Script:

if (ENVIRONMENT.equals("development")) {
return ["dev-config-1.yaml", "dev-config-2.yaml", "dev-config-3.yaml"]
}
else if (ENVIRONMENT.equals("staging")) {
return ["staging-config-1.yaml", "staging-config-2.yaml"]
}
else if (ENVIRONMENT.equals("production")) {
return ["prod-config-1.yaml", "prod-config-2.yaml", "prod-config-3.yaml"]
}
else {
return ["default-config.yaml"]
}

add a Fallback Script:

return ["fallback-config.yaml"]

and in the build step select execute shell with the script:

echo "ENVIRONMENT = $ENVIRONMENT"
echo "CONFIG_FILE = $CONFIG_FILE"

if [ -z "$CONFIG_FILE" ]; then
echo "BUG: CONFIG_FILE is empty"
exit 1
else
echo "CONFIG_FILE selected: $CONFIG_FILE"
fi
Saved the job and build with parameters and check the console output
Earlier:
ENVIRONMENT = development
CONFIG_FILE =
BUG: CONFIG_FILE is empty
After fix applied:
ENVIRONMENT = development(selected env)
CONFIG_FILE = dev-config-1.yaml (selected option)
