Fix docker-compose image tax syntax

[stchris]

This should fix #4001 , which probably broke during a merge.

Looks like the same issue was introduced in this file: https://github.com/alephdata/aleph/blob/main/contrib/keycloak/docker-compose.dev-keycloak.yml

And a similar issue in this file (repetition in the row for global.image.tag):
https://github.com/alephdata/aleph/blob/develop/helm/charts/aleph/README.md?plain=1

Could you fix these, too, before merging? Apart from that, this looks good, thanks for taking care of it.

And could you make sure to cherry-pick these changes onto main afterwards?

I'm confused, but I thought this PR fixes exactly that file?

Will do! Thanks for catching that!

Absolutely, that was the plan (and how I noticed this).

Sorry, you’re right! I somehow got confused in the diff view :/
