Subject: [PATCH] Fix invalid exception syntax: use tuple instead of list

The except clause at line 714 in HashRedactor.apply() was using list
syntax [AttributeError, ValueError] instead of tuple syntax
(AttributeError, ValueError). Using a list causes a TypeError at
runtime: 'catching classes that do not inherit from BaseException
is not allowed'.

This bug would prevent the HashRedactor from properly catching
AttributeError or ValueError, causing the redaction to fail entirely
when these exceptions occur.
