Fixed

• The go.opentelemetry.io/otel/schema/* packages now use the correct schema URL for their SchemaURL constant. Instead of using "https://opentelemetry.io/schemas/v<version>" they now use the correct URL without a v prefix, "https://opentelemetry.io/schemas/<version>". (#2743, #2744)

Security

• Upgrade go.opentelemetry.io/proto/otlp from v0.12.0 to v0.12.1. This includes an indirect upgrade of github.com/grpc-ecosystem/grpc-gateway which resolves a vulnerability from gopkg.in/yaml.v2 in version v2.2.3. (#2724, #2728)
