Plots2: Convert all publiclab repositories' automated tests/checks from TravisCI to GitHub Actions

[jywarren]

Multi-repository coordinating issue:

starting in https://github.com/publiclab/plots2/issues/8793, we developed a plan to move all PL repositories from Travis CI to GitHub Actions, and have made a lot of progress. But there are many repositories still to go, so we are coordinating here.

If you'd like to try, unfortunately the PR must be created by a maintainer (for security purposes) but we'd love help as far as it's possible.

Try looking in the "DONE" section for examples of successful conversions of projects with similar architecture!

NOTE: the PR has to be opened from within the main fork, not from for example jywarren/gh-actions. See https://github.com/publiclab/infragram/pull/157

Hi all - thank you for your support! I'm currently working on this in https://github.com/publiclab/spectral-workbench/pull/647 (my top priority) and in https://github.com/publiclab/mapknitter/issues/1489 (2nd priority). I've made progress on the first but slowly trying to eliminate remaining errors, reading the log carefully each time. Any input/help/tips/support appreciated!!!
