feat: Lumen test matrix

[bishopb]

Description of the change

Adds a test matrix for Lumen, similar to how is done for Laravel in #115. The failures here are all expected, owing to the incorrect handling of session. As a reminder, this pass is meant to document the current state of the integration: later passes will check master against the relevant versions.

I understand the approach, but I believe that CI should never fail. It would be better to mark failed tests as skipped/ignored and backlog the failed results.
