fix(admin): name the WooCommerce integration row (#147)

Saddle Pro's saddle_integration_ui_prefixes hook contributes four
detection-gated prefixes, not three: yoast-, rank-math-, aioseo- and wc-.
#144 gave KNOWN display entries to the three SEO ones and missed the
store, so a Pro + WooCommerce site rendered a row titled literally "wc"
with an empty description via detectIntegrations()'s fallback.

Also regenerates languages/saddle.pot, which was last built on 08-21 and
so was missing #144's six SEO msgids alongside these two.

Closes #146
