Fix typing error

[jwodder]

I suspect the error in question only started being emitted when mypy 1.7.0 was released on the 10th.

for my own sake, so the old one is a tuple of a single str and new one is tuple of strings or tuple with the first element a str?

[jwodder]

tuple[str] is a tuple of length 1 containing a str. tuple[str, ...] is a tuple of any length where all elements are strs.

Mypy was complaining because we we doing this inside the function:

dandi-cli/dandi/cli/cmd_move.py

Lines 88 to 89 in cb86c9c

	if len(paths) < 2:
	raise ValueError("At least two paths are required")

and len() of a one-element tuple is always less than 2, making the line after the raise unreachable.

[yarikoptic]

so it is the

dandi/cli/cmd_move.py:90: error: Statement is unreachable  [unreachable]
        move_mod.move(
        ^
Found 1 error in 1 file (checked 77 source files)
