fix: replace bare except with except Exception

[TrueFurina]

Summary

requests_html.py __convert() (used for cookie conversion) has a bare
except: that swallows everything, including KeyboardInterrupt/SystemExit,
and hides programming errors as if they were expected eval failures.

Replace with except Exception: — same intended behavior (return an empty
kv on eval failure), but unexpected exceptions now propagate.

Verification

• python -m py_compile requests_html.py → OK
• grep -c "except:" requests_html.py → 0 remaining bare handlers

Files changed

• requests_html.py (1 line)
