Jaeger exporter incorrectly exports instrumentation.version

[matej-g]

There appears to be a bug in the Jaeger exporter, in:

opentelemetry-go/exporters/trace/jaeger/jaeger.go

Lines 232 to 237 in ae278e9

	if il := data.InstrumentationLibrary; il.Name != "" {
	tags = append(tags, getStringTag("instrumentation.name", il.Name))
	if il.Version != "" {
	tags = append(tags, getStringTag("instrumentation.version", il.Name))
	}
	}

the instrumentation.version is incorrectly set to instrumentation library name instead of library version.
