metrics version and buildDate appear to be redundant

[olizilla]

We are setting version and buildDate properties manually in metrics.yml. The values are extracted and saved as this.version in the Telemetry instance, but it's never used.

https://github.com/elastic-ipfs/core-lib/blob/314c1ebce6566f7b3f996b7998a38ed9b508759c/src/telemetry.js#L25-L29

They are also set to arbitrary values that do not correspond to the package.version field or the docker image build date tag

We need to identify it these are actually used for anything anywhere, or remove them, as they are a source of confusion. The word on the street is you have to update them to get your metrics to show up. There is no evidence in the codebase I can find to support this.
