[feature]: Support renaming closed cycles

[GauthierPLM]

Is there an existing issue for this?

• I have searched the existing issues

Summary

I noticed two of my cycles are wrongly named and would like to fix their name. However, it does not seem possible at the moment.

I use the community self-hosted version.

Why should this be worked on?

There does no seem to be any way to fix a cycle name at the moment, preventing the fix of any typos noticed after the sprint closed, or a retroactive change in naming format
