Add missing php dependencies for nginx image

[languitar]

Without these dependencies, baikal cannot be used.

Hi @languitar , thanks for the PR - when do you get the error messages that these dependencies are missing? I went through my logs, but couldn't find anything.

Also, could you please also sort the dependencies in alphabetical order and add them to the other Dockerfiles as well?

[languitar]

Sorry for the delay. I have added the dependencies also to the arm nginx image. I am not sure about the apache versions, because I don't use them an I am not sure what is already included there.

I have migrated an existing installation of baikal to the docker image and without these dependencies, first launch failed immediately. I don't have the logs available anymore, though. :/

Maybe @dober knows more about what fails without those dependencies?

Sure!
Without this deps we got an error:
