chore: dynamic copyright year

[siddarthkay]

I ran the help command locally and could not help but notice a hardcoded 2023 in the copyright message. This change ensure the copyright year updates dynamically.

@0xfornax @jshufro @jclapis : As the new year is nearby if you merge this, you'll probably never have to think about an old copyright year in the terminal message.

> ./treegen-linux-amd64 --help | grep  -A 1 COPYRIGHT

Hi @siddarthkay , this repo is no longer in use. Further, I don't think the date is meant to be automatically updated. Software licenses are a complex subject, and best practices seem to vary, but I for one would prefer no dynamic element so the unix strings utility can dump the license verbatim.

Hey @jshufro : Thanks for letting me know about this repo, I was told to use this tool to determine a dry run of reward tree generation of our rocket pool node and thats when i noticed the (c) 2023 Rocket Pool Pty Ltd in --help of this CLI utility.

Do you recommend we use something else for that purpose or is this utility still the recommended way to perform a dry run of reward tree generation?

[jshufro]

The binary for this tool is part of the smart node monorepo now: https://github.com/rocket-pool/smartnode/tree/master/treegen

Thanks for pointing me in the right direction!
Would be good if then someone archived this repo.

Cheers
