Replace all mentions of the octokit action

[hectorsector]

This PR replaces all uses of the octokit action for suggested changes with createPullRequestComment.

This PR will be ready to merge when all the octokit references in config.yml have been replaced.

Closes #21.

@partyshah this is ready for 👀. Some things I'd love for you to review:

• test that the course works and suggested changes are dropped as expected
• file names are what you want

[partyshah]

Just for clarification here, why do we have this? I thought we wouldn't need this since we are not using octokit

[partyshah]

I see this a couple of times later in the file as well.

Great question! We need to explicitly state the issue or PR when the event for the step doesn't provide it.

For this step, it's event: push. A push's payload doesn't contain any information about associated pull requests. Therefore, we need to explicitly state which pull request we want to leave the comment in.

Here's an example where event: pull_request.closed. In this example, the pull_request's payload does indeed contain information about where to respond, so the action doesn't need to explicitly state the pullRequest.

There are a lot of ways we can reference the PR. You've done it by grabbing the pull request from the API, and using that pull request's number. You can also do it by title, since you know it is supposed to be called "Changes".

When I enroll in this course and open the first PR, a debug error is thrown:

@partyshah I think this action needs a pullRequest field for the same reason we discussed above

[hectorsector]

@partyshah we didn't fix this ☝️ did we?

[partyshah]

Fixed conflicts. @hectorsector

[hectorsector]

Strike my last comment, @partyshah. This field is problematic for a couple of reasons:

1. There's no metaPR2 action_id in this step, and
2. Because the event for this step is pull_request.opened, we actually don't need to get the pull request at all.

[partyshah]

Sounds good. I'll fix.
