New release and release pipeline #199

The current main has got some improvement that are great, but the last released version was in 2024. Thus, I think it makes sense to cut a new release.

In the past the releases seem to have been done manually. This is cumbersome and time consuming, and since we now have UV (thanks to @Binbasri-in), we can use a fairly standard release pipeline. I have already built one for https://github.com/ElaadNL/openadr3-client/, so I made a PR for it.
