Update to user tokens (#53)

Per https://central.sonatype.org/news/20240301_changes_to_account_management/#new-publishers-who-will-be-publishing-via-ossrh
(and because we got a 401 error publishing the old way), we now have to use user tokens to publish.

I followed the instructions here: https://central.sonatype.org/publish/generate-portal-token/ and generated a token
username/password pair, which I added to the 1Password entry for Sonatype, and to Github actions secrets.

I think this yml update will cause the publish action to use the new things.
