tests: save plack logs to a file.

Save the plack logs from tests to a file, and then upload that file as an
artifact. This significantly quiets/shortens the output from the tests.

Implement by creating a new plack log environment config `ghaction`.

+# GitHub Actions Workflows
+
+This directory contains workflow definitions for GitHub actions.
+
+## Local Testing
+
+The easiest way to end to end test them is wih a tool such as
+https://github.com/nektos/act (https://nektosact.com/).
+
+```
+$ act --artifact-server-path=/tmp/artifacts
+... actions run here! ...
+```
+
+You can use the `--reuse` flag to reuse information between runs,
+which can speed things up.  `--action-offline-mode` and `--pull=false`
+can be used to test local copies of container images instead.
