feat!: replace Agent starter projects with simpler ones (#3612)

* Add initial setup for "Simple Agent" starter project

- Introduced a new JSON configuration for the "Simple Agent" starter project.
- The flow includes nodes for Chat Input, Chat Output, OpenAI Model, Tool Calling Agent, Calculator Tool, and Python REPL Tool.
- Configured edges to connect these nodes, enabling interaction between different components.
- Added detailed descriptions and configurations for each node to facilitate easy setup and usage.

* Add Travel Planning Agents starter project JSON file

- Introduced a new JSON file for Travel Planning Agents in the starter projects directory.
- The JSON file includes configurations for various nodes such as ChatInput, ChatOutput, OpenAIModel, ToolCallingAgent, SearchAPI, URL Content Fetcher, and CalculatorTool.
- Defined connections between nodes to create a multi-agent system for planning trips.
- Added detailed prompts and configurations for each node to facilitate travel itinerary creation and information retrieval.

* Update example names in newFlowModal to match updated project terminology

* Update agent names in undrawCards component for consistency

* Rename "Complex Agent" to "Dynamic Agent" across frontend and backend components

* format project

* ✨ (Dynamic Agent.spec.ts): Add end-to-end test for Dynamic Agent functionality
✨ (Simple Agent.spec.ts): Add end-to-end test for Simple Agent functionality
✨ (Travel Planning Agent.spec.ts): Add end-to-end test for Travel Planning Agent functionality

* ✨ (Travel Planning Agent.spec.ts): Update end-to-end test for Travel Planning Agent to include new interactions and connections for improved test coverage and functionality.
