Revert the copyright starting year in LICENSE?

[joshwlambert]

The update copyright GHA workflow we use (https://github.com/epiverse-trace/packagetemplate/blob/main/.github/workflows/update-copyright-year.yml) uses the range of years rather than updating a single year. I've been using a single year in Epiverse packages and updating them manually until now.

I assume I should switch to using year ranges to align with the workflow and back-date the first year to the year the project started (which can be easily checked with GitHub)?

All this bearing in mind that the years have little importance: https://daniel.haxx.se/blog/2023/01/08/copyright-without-years/.
