[chore] Downgrade OTEL libraries to 1.20 (#2546)

For some reason httpconv seems to have disappeared from 1.21, which
results in a 1.21 runtime with 1.20 semconv/httpconv which seems to
break some things.

For now, this rolls the OTEL dependencies back to 1.20 which should fix
the observability issues. We'll need to take a look at how to upgrade
safely and correctly in the future.

Relates to #2503.

 ## [1.20.0/0.43.0] 2023-11-10
 
 This release brings a breaking change for custom trace API implementations. Some interfaces (`TracerProvider`, `Tracer`, `Span`) now embed the `go.opentelemetry.io/otel/trace/embedded` types. Implementors need to update their implementations based on what they want the default behavior to be. See the "API Implementations" section of the [trace API] package documentation for more information about how to accomplish this.
