Roadmap to modernize code for D11 + PHP 8.3

Thanks for starting this. I would like and need a D11-compatible version without any other feature changes or updates as I will be migrating our sites to D11 very soon. Other modules have been creating minor updates introducing the bare minimum for D11 compatibility. I was planning on spending some time this month to see how much this module needs for that minimum compatibility and it would be great if we could have at least one release still on the 2 branch without needing to check on updating a whole ton of stuff just for D11 compatibility.

If you can make an MR with the minimum necessary changes to get D11 compatibility while still retaining full backwards compatibility with Drupal 9.3+ then that is very welcome. But let's do that in a dedicated issue, this issue is specifically on future forward changes and does not affect 2.x.

Perfect, I have time planned at the end of the month and early November. I just wanted to make sure we were addressing D11 compatibility in 2 branch as well.

I have made some commits to get this to be minimally D11 compatible. These are unrelated to the other child issues here which appear to aim to clean up and make the code more modern.
