[FR] Duplicate user story

[jceb]

Please describe the problem / need you are trying to solve.

I'd like to duplicate an existing user story with its tasks.

Describe the feature or the improvement you'd like and what are you trying to achieve.

My goal is to quickly split a story that has grown too large into multiple smaller stories. With a duplication feature in taiga, I'd be able to achieve this without much copying text and tasks.

Describe alternatives you've considered

• Manually copy story and tasks, which is very tedious.

Additional context

None.
