Fixes

[error] The configurer for the [otlp] exporter is not registered.
[error] Add the `otel4s-sdk-exporter` dependency to the build file:
[error] libraryDependencies += "org.typelevel" %%% "otel4s-sdk-exporter" % "x.x.x"
[error] and register the configurer via OpenTelemetrySdk:
[error] import org.typelevel.otel4s.sdk.OpenTelemetrySdk
[error] import org.typelevel.otel4s.sdk.exporter.otlp.autoconfigure.OtlpExportersAutoConfigure
[error] OpenTelemetrySdk.autoConfigured[IO](
[error]   _.addExportersConfigurer(OtlpExportersAutoConfigure[IO])
[error] )
[error] or via SdkMetrics:
[error] import org.typelevel.otel4s.sdk.metrics.SdkMetrics
[error] import org.typelevel.otel4s.sdk.exporter.otlp.metrics.autoconfigure.OtlpMetricExporterAutoConfigure
[error] SdkMetrics.autoConfigured[IO](
[error]   _.addExporterConfigurer(OtlpMetricExporterAutoConfigure[IO])
[error] )
[error] org.typelevel.otel4s.sdk.autoconfigure.AutoConfigureError: Cannot autoconfigure [MetricExporters].
[error] Cause: Unrecognized value for [otel.metrics.exporter]: otlp. Supported options [none, console].
