[GH Actions] Create the getReleasePullRequestList Action

If you haven’t already, check out our contributing guidelines for onboarding!

Problem

When a production deploy completes, we need a way to gather all the PRs for that release. That way, we can comment in each that it’s been deployed to production.

Why is this important?

We need a clear audit trail of which PRs are deployed to production. To do that, we first need to know which PRs are being deployed.

Solution

Create a Github Action called getReleasePullRequestList that takes a TAG as input and:

1. Fetch all the Expensify.cash releases.
2. Filter the results to find the release prior to the one with the tag matching the input tag.
3. Execute the getPullRequestsMergedBetween function with the tag found in step 2 and the tag passed as input.
4. Return the result of step 3.

Yes, it returns 30 most recent tags in the first page. Then I’m going to remove 100 limit and use default value.

Do we want to return the PR list or do we want to comment on these PRs with this Github Action as well?

Just return the list 😃

Do you want me to trigger that Github Action once I get merged PR list in my action

Nope, no need!

And thanks, proposal looks go so go ahead and submit the PR
