FIX: Error when length less than 4 in Provider().password() #2176

[DevFoxxx]

What does this change

Adds a warning message and adjusts the password length when the requested length is less than the number of required character categories (special characters, digits, uppercase, and lowercase).

What was wrong

When the password length was less than 4 (for example, 2), the password() function did not ensure that all required character types would be included, leading to unexpected behavior. This caused an error when the length was smaller than the minimum required for character categories.

How this fixes it

The modification checks if the requested password length is smaller than the number of required character categories. In that case, the function automatically adjusts the password length to the minimum value needed to fulfill the requirements for each character category. Additionally, a warning message is printed to inform the user of this adjustment.

Fixes #2176
