Fix code scanning alert no. 1: Clear-text logging of sensitive inform…

…ation (#5)

To fix the problem, we should avoid logging any part of the secret, even
in a redacted form. Instead, we can log a generic message indicating
that a secret is being validated without including the actual secret
value. This approach ensures that no sensitive information is exposed in
the logs.

- Modify the logging statement on line 85 in
`src/python/how2validate/validator.py` to remove the secret from the log
message.
- Ensure that the log message still provides useful information without
exposing sensitive data.
