feat: add assert_compact_debug_snapshot

[jrandolf]

The pretty-print format of debug is generally extremely verbose. It's great for complex objects, but for simple ones, the compact form of debug is far more suitable. This PR adds a assert_compact_debug_snapshot similar to assert_compact_json_snapshot.

@jun-sheaf while we wait for a review — could we merge master and ensure the tests pass?

@max-sixty That error is not related to this PR. Nevertheless, I've added the fix.

The fix is on master so if you merge master it'll resolve...

And the docs break does seem to be from this PR...

Merged — thanks @jun-sheaf . If you want to also add an entry to the Changelog in a PR then great. Otherwise someone can do it when releasing.
