commit89db01ef97added these tracing modules as dependency, but did not require the otlptracehttp module. This module was added later throughf0a29af0f3as indirect dependency for docker/docker. The otlptracehttp and otlptracegrpc modules have no dependency between each-other, but similar to their otlpmetric cousins, are preferred to be on the same version. This patch aligns their versions.
