[new release] trace (4 packages) (0.9)

[c-cube]

A stub for tracing/observability, agnostic in how data is collected

• Project page: https://github.com/c-cube/ocaml-trace

CHANGES:

• add an extensible sum type, so users can implement custom events. For example
  an OTEL collector can provide custom events to link two spans to one another.

Not sure if it's a transient error of the CI but there's currently 404s everywhere. I'vecancelled the build for now.

[raphael-proust]

well there's no 0.9 in https://github.com/c-cube/ocaml-trace/tags nor in releases

so that's probably it

[c-cube]

I reuploaded it. Must have forgotten the dune-release publish step.

Looks to me like these revedeps failures for opentelemetry may be related?

I think from this addition: c-cube/ocaml-trace@4dfa319#diff-200ef699c03562ccea70000ac13fe48441941739e0c1bc622abd8dca5eb24c3eR97

I'll add the upper bound here, then we should be good to go :)

[shonfeder]

Merging since the opentelemetry tests and revdeps are now passing, and all other checks were good or irrelevant before.

[c-cube]

Thank you :)
