0.38 release breaks with latest go.opentelemetry.io/otel/metric

[shane-kerr]

I'm using the latest go.opentelemetry.io/otel/metric, 0.35, which was released last week:

https://github.com/open-telemetry/opentelemetry-go/releases/tag/v1.12.0

From that release:

Metric instruments to go.opentelemetry.io/otel/metric/instrument. These instruments are use as replacements of the depreacted go.opentelemetry.io/otel/metric/instrument/{asyncfloat64,asyncint64,syncfloat64,syncint64} packages.(open-telemetry/opentelemetry-go#3575, open-telemetry/opentelemetry-go#3586)

At least two of the contrib libraries break:

go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc
go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp
