This seems much more complicated since packages may use spdlog and fmt together.

So I will upload NMU to bump spdlog soversion to 1.10.

It's unfortunate that we diverted from upstream with the soversion.
But we'll align with upstream once spdlog 1.11 is released.

@spdlog maintainer, if you disagree with this, there is still enough
time to retract my NMU since it hits the NEW queue.
