v1.19.0 release

Errata

Due to a missing stability attribute in semantic conventions:
open-telemetry/semantic-conventions#1777
the semantic convention network.interface.name was marked as stable during code generation.

Semantic convention network.interface.name should be considered experimental instead,
and will become experimental in the next opentelemetry-cpp release.

v1.19.0 release

Release of:

• opentelemetry-api
• opentelemetry-sdk
• exporter packages
