chore: bump copyright to 2023 and fix wrong copyrights

Issue being fixed or feature implemented

Bump copyright year to 2023-2024

What was done?

run copyright_header.py report and copyright_header.py update
previous work: https://github.com/dashpay/dash/pull/5160/files

How Has This Been Tested?

Please, notice, that copyrights should be updated at the end of year, not at the beginning of year for next years.
That prevent bumping year for files where is only changes in that year - bumping a copyright. This misbehavior can be validated by running copyright_header.py update twice. So, bump 2024 should be done in December 2024, not in 2025.

I wonder if you could make this a scripted diff easily?

[PastaPastaPasta]

I wonder if it would be better for you backdate this commit f653c96 back to 2023 to that we don't have that issue of "bump copyright to 2024 because we bumped copyright to 2023"? We would likely then have to merge via merge commit

Also it appears the scripted diff fails

backdate this commit f653c96 back to 2023

that is a good idea, it works, thanks.
I run script twice and there's no more multiple changes complaining that it's 2024 now.

I tried to set mocked date for commit, and it works locally, but CI still complains: https://gitlab.com/dashpay/dash/-/jobs/6232575556

So, I turned a commit to non-scripted one, have no idea why CI behaves differently.

You could try to script it so.

find . -name '*[sp][hpy]' -type f -exec sed 's/\(Copyright (c) 20..-202\).\( The Dash Core developers\)/\14\2/gi' '{}' \;

add a -i to the sed to make that change into the file.

You could try to script it so.

There's already a script that does it by more advanced way using git history:

contrib/devtools/copyright_header.py update ./

it is just doesn't work fully as expected in CI
