I have updated the outdated https://github.com/acmesh-official/acme.sh/wiki/DNS-API-Test. It now describes how to add security variables to github in 2025.

Now Docker test fails. This is despite the DNS entries being correctly added to hosttech (https://github.com/baerengraben/acme.sh/actions/runs/12955768870/job/36247925398#step:5:3911) and removed again successfully (https://github.com/baerengraben/acme.sh/actions/runs/12955768870/job/36247925398#step:5:7071).

I suspect there is something wrong with the workflow here. Can a maintainer check this?
