fix: bump semconv version to v1.37.0

[paragon]

As we are now using the following v1.38.0 otel packages:

go.opentelemetry.io/otel v1.38.0
go.opentelemetry.io/otel/metric v1.38.0
go.opentelemetry.io/otel/sdk v1.38.0
go.opentelemetry.io/otel/sdk/metric v1.38.0
go.opentelemetry.io/otel/trace v1.38.0

We also need to bump the semconv version provided in generated code.

This is directly tied to v1.38.0 of opentelemetry-go - specifically, open-telemetry/opentelemetry-go#7260, which was included in the v.1.38.0 release (https://github.com/open-telemetry/opentelemetry-go/releases/tag/v1.38.0).

@ernado any chance we can get this in as part of a 1.15.1 release? The current semconv conflicts with the otel packages that are installed, meaning that there will be conflicting schema URLs for anyone using otel in conjunction with the rest of their service (as otel=1.38.0 uses semconv=1.37.0 exclusively).
