Describe the bug

When the branch at the bottom of the stack is merged and the stackit up or stackit down commands are used, a suggestion to restack is provided that reference non-existent commands.

$ stackit up
⮑ new-bottom-branch
Checked out new-bottom-branch.
The downstack branch old-bottom-branch has fallen behind main - you may want to stackit stack restack.

stackit down
⮑ old-bottom-branch
Checked out old-bottom-branch.
This branch has fallen behind main - you may want to stackit upstack restack.

To reproduce

• Create a new base stack on main, make a minor change.
• Create a new stack on the base stack and make another minor change.
• Submit the stacks
• Merge the bottom stack in
• Fetch main git fetch origin main:main
• From the top of the stack run stackit down
• From the bottom of the stack run stackit up
• The suggestions in the previous section will be displayed

Run the following:

$ stackit stack --help
Error: unknown command "stack" for "stackit"

Run 'stackit --help' for usage.

$ stackit upstack --help
