Describe the solution you'd like

Hello,

I would like to propose a feature request for CrewAI to support Jinja2 template formatting in task descriptions. This would greatly increase the flexibility and dynamism in how we assemble task prompts.

Current Situation:
At present, CrewAI's task prompts only supports string replacement, which limits our ability to dynamically adjust prompts based on specific conditions or variables.

Requested Feature:
I suggest that CrewAI supports Jinja2 templates, allowing us to incorporate variables and conditional logic into task descriptions. Jinja2 is a powerful templating engine that enables us to generate task prompts dynamically based on the context.

Expected Benefits:
Increased Flexibility: The ability to customize prompts based on specific task requirements and user inputs.
Enhanced Dynamism: The capability to adjust prompt content dynamically based on real-time data or user interactions.
Improved User Experience: Users will see more personalized and context-relevant task prompts.

Example:

Dear User,
{% if user.is_first_time %}
Welcome to CrewAI! We are delighted that you have chosen us to assist you with your tasks.
{% else %}
Great to see you again! We hope to continue assisting you today.
{% endif %}
Please follow the instructions below to complete the task:
...

I hope this feature can be considered for inclusion in CrewAI, as I believe it will greatly enhance our product experience.

Thank you!
