Fixing Sketches list does not update after renaming a sketch

[Jatin24062005]

Issue:

Fixes #3921

Demo:

Changes:

the reducer logic for ActionTypes.RENAME_PROJECT. Previously, the implementation attempted to update the state directly, but did not properly handle the projects array inside the state.
Now, the reducer correctly:

• Iterates over state.projects using map.
• Matches the project by id from the action.payload.
• Returns a new project object with the updated name.
• Preserves all other projects and the rest of the state immutably.
