Description:
This PR fixes a bug in the password validation logic where the previous script did not properly enforce the presence of uppercase and lowercase letters in passwords.

Changes made:

• Added a new file password_validator_fixed.py in the folder PASSWORD RELATED/password-validator/.

• Updated password validation rules to ensure:

   - At least one uppercase letter
   - At least one lowercase letter
   - At least one number
   - At least one special character
   - Minimum length of 6 and maximum length of 12
   - No spaces
  

Steps to verify:

1. Run password_validator_fixed.py.
2. Enter passwords that meet some but not all criteria.
3. Verify that the script rejects passwords missing uppercase or lowercase letters.
4. verify that valid passwords are accepted.

Notes:

• Original PASSWORD_VALIDATOR.py remains unchanged.
• This fix ensures proper enforcement of password strength requirements as described in the initial rules.

Impact:

• Improves security by enforcing stronger password rules.
• Helps users avoid creating weak passwords.
