<i18n dev> RFR: 8345799: Update copyright year to 2024 for core-libs in files where it was missed

[Magnus Ihse Bursie]

Some files have been modified in 2024, but the copyright year has not been properly updated. This should be fixed. 

I have located these modified files using:

git log --since="Jan 1" --name-only --pretty=format: | sort -u > file.list

and then run a script to update the copyright year to 2024 on these files.

I have made a manual sampling of files in the list to verify that they have indeed been modified in 2024.
