[Helm/Release] Support local path

[cynial]

Currently Helm/Chart support path：

		_, err := helmv3.NewChart(ctx, "wpdev", helmv3.ChartArgs{
			Path: pulumi.String("./hello"),
		})

But Helm/Release doesn't support：

		rel, err := helmv3.NewRelease(ctx, "test", &helmv3.ReleaseArgs{
                         // No Path args for Release
			RepositoryOpts: helmv3.RepositoryOptsArgs{
				Repo: pulumi.String("./hello"),
			},
		})
---
throw error:
          failed to pull chart: could not find protocol handler for:

Is it possible to support path for Helm/Release? Thanks.

In the helm release resource go code, it looks like if the chart name starts with a "/", it interprets the chart as a local file. However, RepositoryOpts are treated as mandatory (by the python SDK at least), so that won't work either (and passing an empty RepositoryOpts struct isn't accepted either.

@viveklak Is there a way forward here?

There's no technical reason we can't support this. The current implementation appears to be making some bad assumptions, but it's fixable. I'll go ahead and pull this into the current milestone since I'm working on related code.
