cool production release pull requests

Simple script to facilitate production releases.

What it does:

• Creates a pretty list of merged PR:s and ninja-commits to master
• Creates a production release branch named production-release-DATE-[RUNNING-INDEX] and pushes it
• Creates a PR from the production release branch to production, with the aforementioned list as description

What it doesn't do yet:

• Prepend the PR description to CHANGELOG.md (there's an ugly 0.0.1 of that commented out in code)
• Customization

Assumptions:

• Production lives in branch called production
• You want the current local master to go to production
• Prerequisites: GitHub CLI

How to use:

• have this repo cloned somewhere (yes it's not very polished), in this example it's in /codez/cool-pr-pr
• be in your own repo
• make sure your local master is the thing you want to release
• run /codez/cool-pr-pr/release.sh
• edit the proposed PR description to your liking
• done! the link to your brand new PR PR is printed for you, have fun
