Write a Python function `find_rotations(s: str) -> int` that determines the minimum number of rotations (greater than 0) required to return a string to its original form. A rotation involves moving the first character of the string to the end.
#### Example Usage
```python [main.nopy]
find_rotations("aaaa") # Output: 1
find_rotations("ab") # Output: 2
find_rotations("abc") # Output: 3
```
#### Constraints
- The input string will have a length of at least 1 and at most 1000 characters.
- The string will consist of lowercase English letters only.def find_rotations(s: str) -> int:
"""
Determine the minimum number of rotations required to return the string to its original form.
Args:
s (str): The input string.
Returns:
int: The minimum number of rotations.
