Bumps go.opentelemetry.io/collector/pdata from 1.50.0 to 1.51.0.

Release notes

Sourced from go.opentelemetry.io/collector/pdata's releases.

v1.51.0/v0.145.0

End User Changelog

💡 Enhancements 💡

pkg/scraperhelper: ScraperID has been added to the logs for metrics, logs, and profiles (#14461)

🧰 Bug fixes 🧰

exporter/otlp_grpc: Fix the OTLP exporter balancer to use round_robin by default, as intended. (#14090)

pkg/config/configoptional: Fix Unmarshal methods not being called when config is wrapped inside Optional (#14500) This bug notably manifested in the fact that the sending_queue::batch::sizer config for exporters stopped defaulting to sending_queue::sizer, which sometimes caused the wrong units to be used when configuring sending_queue::batch::min_size and max_size.

As part of the fix, xconfmap exposes a new xconfmap.WithForceUnmarshaler option, to be used in the Unmarshal methods of wrapper types like configoptional.Optional to make sure the Unmarshal method of the inner type is called.

The default behavior remains that calling conf.Unmarshal on the confmap.Conf passed as argument to an Unmarshal method will skip any top-level Unmarshal methods to avoid infinite recursion in standard use cases.

pkg/confmap: Fix an issue where configs could fail to decode when using interpolated values in string fields. (#14413) For example, a header can be set via an environment variable to a string that is parseable as a number, e.g. 1234

pkg/service: Don't error on startup when process metrics are enabled on unsupported OSes (e.g. AIX) (#14307)
