Add linux/arm64 support for the operator OCI image

[Danielduel]

Add linux/arm64 as a target for the operator being usable on arm64 boxes such as raspbery pi. This relies on a change being made to the action repository.

I'm currently investigating why the CI fails against your fork's PR.
Nevertheless, the CI will pass regardless of your change.

I will merge this and release v0.5.0 in the afternoon.

@Danielduel could you please sync this PRs fork branch with main so we can see if the CI works now?

[ThoSap]

I changed the PR name as when it is merged it will be in the release notes.
Once you synced main to your forked repo branch and the tests run through, I'm going to approve this PR.

I am away from my pc right now, I will do it much later today.

No worries, that's ok.

Can you click the "Squash and Merge" button?
If you are unable to due to lacking permissions I can do it.

Once this is merged, I will release v0.5.0.

@Danielduel sorry for all these questions.
It is my first interaction of a community PR with a open source repository that I "own".
And again I learned so much 👍🏼
The release workflow is running.

You did well!
I suggest adding yourself to maintatainers list, because my first reaction was "who is this, this person is not mentioned in 'people' section of the organization"

Thank you for supporting me along the way!
