wiktionary: regression in handling unknown words

[dgw]

sopel-wikimedia 1.0.0's version of the wiktionary plugin outputs an uncaught exception when queried for words that don't exist on the wiki:

14:39:01 <dgw> .wt jfoawyeriasf
14:39:02 <Yuzu> Unexpected HTTPError (404 Client Error: Not Found for url:
                https://en.wiktionary.org/w/index.php?title=jfoawyeriasf&printable=yes) from dgw.
                Message was: .wt jfoawyeriasf
14:39:12 <dgw> .version wiktionary
14:39:12 <Yuzu> [version] wiktionary v1.0.0

Compare to Sopel 8.0.4's built-in wiktionary:

14:38:49 <dgw> .wt jfoawyeriasf
14:38:50 <Sopel> dgw: Couldn't get any definitions for jfoawyeriasf.
14:39:01 <dgw> .version wiktionary
14:39:01 <Sopel> [version] wiktionary v8.0.4 (built in)

The standalone plugin has a response.raise_for_status() call not present in the original, but no corresponding try/except block to catch the error where wikt() is called.

I initially thought this was a bug with handling spaces in the query, but I'm glad I held off opening the issue and took time to test a bit more.
