Fix skeleton validation error should have required property id

[jcandan]

Describe the bug

Running coderoad build gives a skeleton validation error: should have required property 'id', even after a coderoad validate success.

$ coderoad validate
...
--- Running setup test...
--- Loading solution commits...
--- Running solution test...

✔ Success!
$ coderoad build
Building CodeRoad tutorial.json...
Validation error at  - should have required property 'id'
Skeleton validation failed. See above to see what to fix

To Reproduce

I was getting this having completed the tutorial up to Build the config.json file.

I was able to reproduce this with one of the available example projects.

Note: I did need to capture all the branches, and I provide a loop to do that.

git clone git@github.com:coderoad/fcc-learn-npm.git
cd fcc-learn-npm/
for remote in `git branch -r`; do git branch --track ${remote#origin/} $remote; done
coderoad validate
coderoad build

Expected behavior

A successful build.

I found the solution.

Reading through the skeleton schema, I found the following:

    id: {
      type: "string",
      description: "A unique identifier for your tutorial. Currently no system to create this, so create your own for now",
      examples: ["fcc-learn-npm"]
    },

When I added id: 'fcc-learn-npm, it allowed the coderoad build to succeed.

I'll create an issue to address this in the examples and tutorial.
