List OpenTelemetry API and distribution versions with published Lambda Layer version ARNs

[dude0001]

Looking at the contribution guide releasing a layer section it appears the release build, publishing of a new Lambda Layer version and publishing those versions in the signalfx/lambda-layer-versions repo is an internal process. The Lamba Layer versions publish are not very helpful by themselves. You cannot tell which version of the OpenTelemetry API and distribution/instrumentation packages you should use.

So for example right now https://github.com/signalfx/lambda-layer-versions/blob/main/splunk-apm/splunk-apm.md shows the latest version of the Layer for us-east-2 is arn:aws:lambda:us-east-2:254067382080:layer:splunk-apm:365. If I try to run my application on this Layer without upgrading the API and distribution/instrumentation packages, I can get runtime errors like below that show there is a conflicting version in the site packages compared to what is deployed with the Layer 0.32b in site packages instead of the expected 0.36b in the Layer here.

There is also a log give like [splunk-extension-wrapper] splunk-extension-wrapper, version: 4552de7 that does appear to be a commit hash back to signalfx/splunk-extension-wrapper. You can reverse engineer from the error message or the commit what version of the API and instrumentation packages you need to upgrade your application with to match the layer.

It would be very helpful if the published Lamba Layer versions were published with the API and distribution versions that are included. It appears this needs to come from within the internal release process mentioned in this repo.
