deno task from workspace module is not resolving the module

[ansemb]

Hi,

I wanted to try out deno in our repo by first converting our tools to use deno.

I've added a simple repro here:

deno-private-npm-repro.

I added a workspace with the tool:

{
  "workspace": {
    "members": ["./modules/some-other-tool"]
  },
  "tasks": {
    "hello": "deno run @mynamespace/some-other-tool",
    "hellojsr": "deno run jsr:@mynamespace/some-other-tool",
    "hello-rel": "deno run ./modules/some-other-tool/index.ts"
  },
  "imports": {
    "@mynamespace/some-other-tool": "jsr:@mynamespace/some-other-tool"
  }
}

Then I want to use this tool inside some of the packages/* e.g. ui.

I would expect deno run @mynamespace/some-other-tool (or deno run jsr:@mynamespace/some-other-tool) to resolve to modules where the tool resides.

❯ cd packages/ui

❯ deno task deno-hello
Task deno-hello deno task --cwd . hello
Task hello deno run @mynamespace/some-other-tool/index.ts
error: Module not found "file:///<user>/code/repos/deno-private-npm-repro/packages/ui/@myn

NOTE: Running the tool with a relative path works deno run ./modules/some-other-tool/index.ts, however, we need to set the cwd from the package from which the tool is running when running with deno task <> from this package. Or, we would need a relative path from the package to the tool, which seems a bit cumbersome.
