[Go] Bump to newer semconv

[pellared]

Required because of open-telemetry/opentelemetry-go#4754 (part of https://github.com/open-telemetry/opentelemetry-go/releases/tag/v1.22.0).

Do you think that here

opentelemetry.io/content/en/docs/languages/go/getting-started.md

Lines 196 to 202 in 6e3bf58

	func newResource(serviceName, serviceVersion string) (*resource.Resource, error) {
	return resource.Merge(resource.Default(),
	resource.NewWithAttributes(semconv.SchemaURL,
	semconv.ServiceName(serviceName),
	semconv.ServiceVersion(serviceVersion),
	))
	}

it would be better to use resource.NewSchemaless instead of resource.NewWithAttributes to mitigate problem that the users would have when bumping OTel Go?

non blocking comment, @open-telemetry/go-approvers: we can implement an automatic version updating similar to what java, collector, etc have:

• https://github.com/open-telemetry/opentelemetry.io/blob/main/.github/workflows/auto-update-versions.yml

• opentelemetry.io/content/en/docs/languages/java/_index.md

This could be nice. However, take notice that the version is not equal version of OTel Go. It may not be easy to create such script.

Also for java we have different versions for SDK, semconv, etc. So we might be able to replicate that.

I also created open-telemetry/opentelemetry-go#4846 so that at least the example would not break in runtime if the code uses an older version of semconv.

@pellared feel free to merge when you feel you've gotten enough feedback from other folks on the Go SIG for your question. Otherwise, I'll plan to merge by end of week.

@cartermp Can you merge it? This one is a trivial fix. It just propagates the changes: https://github.com/open-telemetry/opentelemetry-go/blob/main/example/dice/otel.go#L29

I will propose a solution that does not require bumping semconv package.. This one would require more approvals from the Go SIG.

Sounds good.
