[GH Actions] Create the markPullRequestsAsDeployed action

Problem

There is no obvious audit trail on Expensify.cash pull requests that show us whether they’ve been deployed.

Why is this important?

Right now, this isn’t a super critical issue because PRs are always deployed when they’re merged. But soon, that won’t be the case. Furthermore, right now we’re only deploying once, directly to production, but soon we’ll be deploying pull requests first to staging, then to production.

Solution

Create a Github Action called markPullRequestsAsDeployed that takes the following inputs:

1. PR_LIST: Array<Number> – The list of PR #’s to comment in
2. IS_PRODUCTION_DEPLOY: Boolean

And it will use octokit.issues.createComment to comment on every PR in the list stating that it was deployed to staging or production.

To be considered complete

• You must provide documentation that this has been tested in a separate repo (or a fork of Expensify.cash) as is working as expected.
• Just because the PR is merged doesn’t mean that your work is done. We need to make sure that it’s working as expected with a live test in Expensify.cash.

Internal issue Upwork posting

@mikeattara Your proposal looks good. I’d like to see automated unit tests of the comments, too.

My proposed solution:

• Loop over the PR_LIST
• Check if each PR is merged to the master or staging branch based on the IS_PRODUCTION_DEPLOY value
• Write a comment on the PR stating whether the PR has been deployed on production or staging
