Identifying unused snapshots

[epenet]

Is your feature request related to a problem? Please describe.

We know there are unused snapshots, but it is very hard to identify where they are.

Describe the solution you'd like

It would be nice to have a way to identify the individual unused snapshots

Describe alternatives you've considered

Additional context

See home-assistant/core#128162
Due to xdist incompatility, we are unable to identify the unused snapshots as soon as they enter the codebase.

There's a --snapshot-details flag you can pass to pytest. See https://github.com/syrupy-project/syrupy#cli-options. Let me know if that's sufficient for your use case.

It would be sufficient if it worked with xdist... but that doesn't work.
I've started work on #901, and it kind of works on my machine but I can't get it inside the Home Assistant CI
