Update corpus tests

[shaobo-he-aws]

Description of changes:

These tests should include entity tags.

Should we be concerned about the size of the corpus tests tar shrinking by -732 KB (72%)?

Per John's comment, we could run the script authored by @khieta to analyze the differences between the corpus tests. It's in the scripts/ directory in this repo.

Looks like they're run in CI:

Based on comparison script output, I'm not concerned about the decrease in compressed corpus size
