[CI] Explicitly run tests on minimum supported version (#57)

* [CI] Explicitly run tests on minimum supported version

This ensure consistency with the minimum version declared in the project file.

* [CI] Drop running tests on Julia v1.11

We ideally interpolate between `min` and `1.12` and hope everything goes well.
