Actions to add

[Aariq]

In addition to "hello world" for R and the basic "run an R script that either errors or doesn't":

• [x] validation as tests with testthat??? (see https://github.com/weecology/PortalData/blob/main/.github/workflows/main.yml)
• [x] validation as Quarto report rendered to GH pages
• [x] render something to github-flavored-markdown
• [x] something that uses matrix and runs in parallel
• [ ] something that uses rclone to read and/or write data to Box
• [ ] something that makes sense to run on a cron job (e.g. makes a GitHub release?)

also possibly something that creates a GitHub release on a cron job (for integration with Zenodo)
