Closes #122

I haven't tested this out (so maybe wrong), but I wonder if we should configure this via these env vars.

This looks like it'll also cause it to be exposed elsewhere, e.g. metrics (setup).

These are compile time env vars (env! Macro) not runtime so i dont think those will work. Can test tmr

Would be great to figure out how to override the version tag on metrics, as that's what our internal dashboards use

Ah I think we may actually be able to use https://github.com/paradigmxyz/reth/blob/6f96a328128eb79a3009669b0a32f232971a99c9/crates/node/core/src/version.rs#L15 to override it entirely on our own. I will do a separate PR and close this one once I can test it works.
