readonly mount

[JackCaster]

the mount property in the devcontainer.json as described here https://containers.dev/implementors/json_reference/#general-properties accepts a list of <property>:<value>. How can I flag the mount to be readonly using this type of definition?

Most often, the mount instruction is a one-liner (https://code.visualstudio.com/remote/advancedcontainers/add-local-file-mount), and in that case I can specify the readonly flag like

"mounts": ["source=...,target=...,type=bind,readonly]

I can workaround the limitation with

"mounts": [
    {
      "source": "...",
      "target": "...",
      "type": "bind,readonly",
    }
  ]

but in this case the linter will complain that the property type is not correct

Value is not accepted. Valid values: "bind", "volume".
