Fix Quickstart script

Description

Removing redundant command after gcloud CLI migration in #610

The automated migration revealed a duplicate command line, and presumably the gcloud CLI has fixed the parallelism problems.

Code Review

This pull request simplifies the script by removing a redundant gcloud storage cp command, which was likely a workaround for a previous issue. While this is a good simplification, the current implementation will silently ignore failures during the file upload and incorrectly report success. I've suggested a change to properly handle the command's success or failure, providing clearer feedback to the user and making the script more robust.

[gemini-code-assist]

The current implementation suppresses errors and continues execution, which means a failure to upload files will go unnoticed while the script reports success. This can be misleading and make debugging difficult. It's better to check the exit code of the command and provide appropriate feedback to the user.

Suggested change

	gcloud storage cp learner_context/*.txt "gs://${CONTEXT_BUCKET}/learner_context/" 2>/dev/null|| true
	echo " Learner context uploaded to gs://${CONTEXT_BUCKET}/learner_context/"
	if gcloud storage cp learner_context/*.txt "gs://${CONTEXT_BUCKET}/learner_context/" >/dev/null 2>&1; then
	echo " Learner context uploaded to gs://${CONTEXT_BUCKET}/learner_context/"
	else
	echo -e "${YELLOW}Warning: Failed to upload learner context files. The demo may not be fully functional without them.${NC}"
	fi

Yes, ideally this wouldn't ignore errors, but the original script did. Should we just take off the || true?

yeah maybe. I am not sure where this sample came from
