[ty] ecosystem-analyzer: Inline diffs and panic messages (#24015)
## Summary
Pulls in some ecosystem analyzer changes that allow us to see diagnostic
diffs inline (will be collapsed into a `<details>` block if there are
more of them, and will be randomly sampled if there are too many of them
to fit inside a comment):

And we can now see panic messages in the HTML report:
