CURL error 28 on certificate creation/renewal about acme-companion

@Steiniche : #1084 (comment)

There is a known issue with the version of curl currently shipped with Alpine 3.19 and 3.x kernels, causing an endless loop to hang containers, usually on startup. The 3.x kernel line has been End of Life since 2017, but some prebuilt systems such as older Synology NAS units are still running it.

While a fix has been applied to the affected upstream library we do not have an ETA for if or when it will find its way into the version of curl shipped with Alpine 3.19.

I am seeing something very similar with 2.2.9
When the Acme Companion starts it correctly outputs its version number and then nothing.
Running with DEBUG=1 yield no more logs.

Trying to execute docker exec acme-companion /app/force_renew the command just hangs indefinitely.
As it seems 2.2.9 has updated many dependencies based on depandabot recommendations maybe this is the culprit?

I tried introducing a fault where the Acme Companion did not know of the nginx-proxy container by not:

1. Providing the volumes-from directive
2. Providing the label
3. Providing the env var

This still did not give any error messages.

I have reverted back to 2.2.8 for now as this has fixed the problem.
Further, 2.2.8 will provide error messages for what to do when in a faulty state as described above.

Happy to help test what ever is necessary to find the problem.
