I have a use case, where I’m using zio tapir and sttp in same module, but AFAIU, I have an issue with tapir 1.13.32:

```auto
version conflict(s) in library dependencies; some are suspected to be binary incompatible:

* dev.zio:zio-json_3:1.0.0 (early-semver) is selected over 0.10.0 for compile
  +- dev.zio:zio-schema-json_3:1.8.7 (depends on 1.0.0)
  +- com.softwaremill.sttp.tapir:tapir-json-zio_3:1.13.32 (depends on 0.10.0)

```

AFAU, “com.softwaremill.sttp.tapir” %% “tapir-zio-http-server” % “1.13.32” pulls this “dev.zio:zio-json\_3:1.0.0” dependencies.

I am missing something ?
