add implementation of permissions inputs

[gr2m]

This is ready for review now.

Our tests now log out each request, including request body for the POST request to create an installation access token. That way it becomes part of our snapshot and we can verify that the correct requests are being sent.

I don't like the way I implemented the logging, it's manually on every .intercept() call. And I had to use a hack with a once() helper method because the body() and path() callbacks get invoked twice by undici for some reason. Ideally there would be a way to add a "request" listener and just log that out, I'll ask the undici folks if there is a way, I couldn't find any.

Anyway, this is now good for merging

I think we can merge this one in already, and continue next week investigating the double requests in the snapshots

This is good to go.

We are exporting the promise returned by main() for testing. We need to await the execution in order to snapshot all requests that were sent by it.

Thanks so much, @gr2m! ✨ I left a few minor suggestions for your consideration.

let's ship it 👍🏼

What's the benefit of using console for code snippets?

```console

I have never seen that used before

It adds syntax highlighting. You can use sh-session or console for command line snippets, which will display differently than shell or bash, which are better suited for scripts.

No syntax highlighting:

> echo $FOOBAR
Hello World!

Syntax highlighting with console:

> echo $FOOBAR
Hello World!

Syntax highlighting with shell:

> echo $FOOBAR
Hello World!
