add setting for a default --platform parameter on docker command line

[giallu]

I work in OSX but my target platform is based on linux/amd64 so all of my images does not include the linux/arm64 variant.
For this reason I need to add "--platform=linux/amd64" to all docker commands, which is supported in settings.json but ONLY for 'docker.commands.{build,run,runInteractive}

as a result, I get this when using other commands like "pull"

Executing task: docker image pull ghcr.io/moldiscovery/centos7:latest 

latest: Pulling from moldiscovery/centos7
no matching manifest for linux/arm64/v8 in the manifest list entries

So I think "pull" should also support customizing it's command or, even better, having a global setting that applies to all commands so I can add "--platform=linux/amd64" there
