settings: Use HTML table for "Alert Words" for better icon alignment.

"Alert Words" is one of Zulip's oldest settings UI elements, and as a
result is buggy.  This commit converts it to use our standard
progressive-table-wrapper system used for settings tables, which has
the side effect of fixing a bug that mad ethe tables look pretty bad
if one adds a very long word.

Fixes #17172.
