I don't think we should add this because it is confusing.

AFAIK, we get this agent version from package.json. But that is inaccurate for VSCode insider builds, because it just identifies the previous stable version (typically.)

Also for the JetBrains stable release, we have been making the stable release as a respin of the last prerelease without necessarily merging the package.json changes.

If we can make the agent versions accurate, that's great. But let's not log something that is probably wrong or at least confusing.

@dominiccooney So I talked to @abeatrix and turns out that the package.json for the insiders-release and proper release is automatically adjusted and that writes the value of agentExtensionVersion and you can see that in the cody settings too

NOTE: We already have these being emitted in Webviewopentelemetry service so we have this in honeycomb
