Improvement for https://www.pulumi.com/learn/building-with-pulumi/stack-references/

When creating reference to the stack of my_first_app, the stackRef variable is built with a kebab-cased project name (my-first-app):

const stackRef = new pulumi.StackReference(`${org}/my-first-app/${stack}`)

However, this project was created with a snake_cased name in Creating a Pulumi Project. (mkdir my_first_app)

This leads to the following error when running pulumi up for the my-second-app-staging stack:

     Type                             Name                            Plan       Info
 +   pulumi:pulumi:Stack              my-second-app-staging           create     1 error
     └─ pulumi:pulumi:StackReference  etigrln95/my-first-app/staging             1 error

Diagnostics:
  pulumi:pulumi:Stack (my-second-app-staging):
    error: preview failed

  pulumi:pulumi:StackReference (etigrln95/my-first-app/staging):
    error: Preview failed: unknown stack "etigrln95/my-first-app/staging"

Using snake_cased project name works correctly:

const stackRef = new pulumi.StackReference(`${org}/my_first_app/${stack}`)

I suggest using kebab-cased name when creating the my-first-app directory in the first tutorial to keep a consistant naming.

Thank you @eguerlain for submitting this issue! We will be taking a look into this. We do have an updated guide available for Stack Outputs and References if you'd like to check that out in the meantime.
