fix: replace 4 bare except clauses with except Exception in jsdate.py

[koteshyelamati]

Bare except: clauses catch BaseException, including SystemExit and KeyboardInterrupt.

In jsdate.py, 4 bare except: clauses wrap datetime conversion and formatting calls:

• to_local_dt() and to_utc_dt() can raise OverflowError (out-of-range dates), OSError (pre-1970 dates on Windows), or ValueError
• dt.strftime(pattern) can raise ValueError for unsupported patterns or UnicodeEncodeError

All four convert any exception into a JavaScript-style MakeError('TypeError', ...). Using except Exception: correctly covers all these cases while still allowing KeyboardInterrupt and SystemExit to propagate.
