Release a stable version, get security coverage

Problem/Motivation

This module hasn't seen any updates in a while and I think this is a good sign, as there are no actual open bugs for Drupal 10.x, and a few dozen sites report using it.

Therefore, I think it can be considered feature complete.

Remaining tasks

I'd like to see a stable release of this module and, what's more, security coverage for it, please!
Given the very manageable size of the code base, I think this should be pretty straightforward.

Thank you to all who contributed and made this module possible!
