Fix dependencies to unreleased sdk/logtest (#6800)

Fixes https://github.com/open-telemetry/opentelemetry-go/issues/6801

`sdk/log/logtest`, which is exported into its own module, is also not
released.
Yet the package upgrade turned it into its own version, which went
unseen because the local import is using a replace statement.
For some reason, this also wasn't triggered when I [checked the contrib
repo](https://github.com/open-telemetry/opentelemetry-go-contrib/blob/main/RELEASING.md#verify-otel-changes).

I believe we need to cut 0.12.1 for those three modules.
