[bugfix/tracing] fix broken tracing due to conflicting schema url (#2712)

The OpenTelemetry SDK is very strict about the schema version when
the `Resource` is initialized.

Specifically, different schema versions _CANNOT_ be mixed, and since
the default SDK resource (which is merged with the user-defined one)
defines a schema URL, the `semconv` imports are really prone to being
out-of-sync.

The best way to avoid this is to merge a _schemaless_ resource. This
is fine...there's plenty of other ways to get `semconv` out of sync,
and the core service attributes (e.g. `service.name`) should not ever
change.

Additionally, any errors here are now propagated so that they'll be
visible instead of silently swallowed.
