CI failing with Augur 25.3.0

Noticed on this run from #1106:

Run cram --shell=/bin/bash tests/sanitize-metadata.t

-  ERROR: None of the possible id columns (['strain']) were found in the metadata's columns ('Virus name', 'gender', 'date', 'gisaid_epi_isl')
+  ERROR: None of the possible id columns ('strain') were found in the metadata's columns ('Virus name', 'gender', 'date', 'gisaid_epi_isl')
   [1]

Fix is simple, I'll update the output text to match.
