Add docker image for ARM

Type of pull request:

• Bug fix
• Feature

Description:

This change should be enough to cross-compile to both AMD and ARM.
It's complex for me to set up all the tokens and registries in my fork to test it though, so let's come up with a testing strategy.
I've been doing this successfully in my BOT's repo

Closes #988

We can run the workflow in a branch and create a docker with a special name (e.g. lichess-bot-devs/lichess-bot:arm). Would that be enough for you to test it?

Sure, something like that sounds great, I have both amd and arm linux vms available so I should be able to compare both versions from the same branch. Feel free to mingle with this branch to add the required name changes to ensure images aren't confused with the master ones.

The workflow failed (see the run here) with error:

ERROR: Multi-platform build is not supported for the docker driver.
Switch to a different driver, or turn on the containerd image store, and try again.

If you can't fix the multi-platform build (I don't know how hard it is to fix), then creating different dockers for amd and arm seems fine.

Can you try again @AttackingOrDefending? I added two missing steps to prepare the multi-platform build.

[AttackingOrDefending]

Done. They were created and uploaded to GHCR and docker hub.

The one tagged with arm works for me!

There's only one change I had to make, because originally I got this error about the version: harcoding a numeric version in

lichess-bot/lichess-bot.py

Line 1191 in 6aff6a9

this_lichess_bot_version = version_numeric(__version__)

But that has to do with your change in versioning.yml to test, so I'd say all good!
