style(quickadapter): tighten tail probe docstring clause (c)

The (c) clause previously named both `ValueError` and
`UnicodeDecodeError` plus their subclass relationship. The exception
classes are visible at the `except ValueError` line below — keep the
behavioral description in the docstring ("not parseable by
json.loads (malformed JSON or invalid UTF-8)") and let the code
document the catch surface.
