Github Actions are super powerful and yaml is super confusing

(refer to my previous post: Simon Willison:Git scraping: track changes over time by scraping to a Git repository aka how to use github actions to call an API every 20 minutes)
I want to read Firefox Desktop support questions every 15 minutes roughly so I can generate infographics every hour. To do this:
- I modified my trusty get-creator-answers-questions-for-arbitrary-time-period.rb (compare with api2’s get-creator-answers-questions-for-arbitrary-time-period.rb ) as follows:
  - awesome_print is no longer maintained but there is a fork called amazing_print which I switched to.
  - Fixed two long standing bugs that I just discovered : 1. Kitsune issue 3686 didn’t work for both PST and PDT so I wrote KludgeTimeFromBogusZtoUTC(pst_in_utc_str) 2. updated was wrongly using the uncorrected time!
- Created a github action, getffquestions.yml to run get-creator-answers-questions-for-arbitrary-time-period.rb every 15 minutes and create a CSV file using Ruby 2.7
In the process I found out that like Heroku in 2007 :-), you can create servers at will with Github actions and those servers can basically run anything on Windows, Mac or Linux!
I also learned that I dislike YAML :-) Too loosey goosey! For a good time try and figure out what |- means. This is just one of the many things that are vexing!
Next thing to do: create a second github action to create infographics using R or Ruby every hour
