ci: tests

[a-frantz]

Lots of lines/files changed here but nothing huge. Most of the changes are related to changing names/paths for our test files to be a little clearer in their contents. There's still some room for improvement there.

I've also added a tests/workflows/input_json/ directory with some files that aren't hooked up to anything yet.

Includes some minor bug patches. Perhaps controversial, I changed our a longstanding convention for our star_db files. These are now expected to be "flat archives" (without a root directory). This makes us robust to the annoying case where the tar archive's filename doesn't match the inner contents.

This CI test isn't working as expected - https://github.com/stjudecloud/workflows/blob/main/.github/workflows/lint-check.yaml#L43

It should be failing because I'm currently using a branch-tests tag but it is passing. Will take a look tomorrow.

Last 3 commits broke the CI in an expected way. We should consider the CI green. Here's why:

• Update lint-check.yaml fixed the broken lint-check CI and it started catching the usage of branch-* images (and OOD util images 😬 )
• fix: bump to latest util image fixed the OOD util images, but the branch-* tags were still in use so that continued to fail
• chore: don't use branch image fixed the lint-check CI but now the STAR tests are failing, as they are trying to pull an image which doesn't exist (and won't exist until this merges into main)
