Gather new benchmark data

[countvajhula]

Summary of Changes

We could use this to gather the new benchmark data using GitHub's CI infrastructure.

Things we would need to do:

1. Publish the new benchmarks suite as a package on the Racket Package Index (takes about 10-15 minutes to appear, once published)
2. Address the "TODO"s in the new workflow file.

It should then publish the new benchmarks on GitHub Pages at <root URL>/qi/competitive-benchmarks

Another possibility is we could have the make new-benchmarks target only generate text output data to STDOUT. Then we could manually copy it in the job UI, and feed it into the charts manually.

This PR has a lot of noisy commits for testing, so squash-merging this one. Changes were OK'd in today's meeting.

Woops! When I saw the force-push, I was hoping you'd rebased and dropped the noise commits :)
