docker not supported in vscode manifest extension

[cheahkhing]

Unknown property 'docker' for type 'Application'.

According to https://docs.cloudfoundry.org/devguide/deploy-apps/manifest-attributes.html#docker, docker should be supported.

I'm closing this as a duplicate of this other issue which covers the same problem:

#330

Sorry... I jumped to the wrong conclusion there. The issues are similar but distinct. This one is about the CF manifest editor, whereas the other one is about the CF resource in the Concourse editor.
