Migrate to new unison images fixes #810

[EugenMayer]

Migrate to new unison images which are build for amd64/arm64 using manifests. This will fix #810

• add ruby 3.0 to test matrix

Since there are currently no CI engines available to run MacOS on M1, nor any MacOS offering CI that runs docker-for-mac (license issues), i cannot test docker-sync on it's home platform in the CI and thus rely on the community to do that testing - i do no longer own a mac

@EugenMayer I see the gem version needs to be updated.

[EugenMayer]

@yoseph1998 you need to compile / run from source, yes

[yosephsa]

@EugenMayer Yes, I have this branched cloned locally and I am running ./deploy_locally.sh

I updated the version locally to 0.7.3 so that I can validate the installed docker-sync is the one from this branch.

I was only able to make this work with the changes proposed above (adding ghcr.io/)

[EugenMayer]

change the value in https://github.com/EugenMayer/docker-sync/blob/main/VERSION to 1.0.0 and run deploy locally again. be sure to run gem uninstall docker-sync before that

[yosephsa]

@EugenMayer Yes, that's what I am doing (on task/new-unixon-images, not main) and getting the following error because the image in unison.rb and native_osx.rb do not specify the ghcr.io/.

If I update those files to use ghcr.io/eugenmayer/unison:2.52.1-4.12.0 Everything works correctly.

[EugenMayer]

Really odd i missed that after i actually already worked on those lines .. kind got lost over it.

Fixed it, could you try once again?

[yosephsa]

@EugenMayer Tested and working locally (M1 MacOS). Thank you!

[yosephsa]

I don't see the version being updated in this PR, is that happening outside of the MR?

[EugenMayer]

Yes @yoseph1998 version will be planned when the release is planned. Which will happen very soon

[yosephsa]

@EugenMayer Great. All LGTM. Again thank you for all this work!

[EugenMayer]

Your welcome, you did a fair share of this too. Thank you
