CI: Use uv's resolution=lowest strategy in one of the jobs (#95)

Instead of manually specifying the lowest supported aiida-core
version in CI specification, we can use the uv's resolution algorithm
to test with the lowest supported versions of the dependencies.

* CI: Use uv's resolution=lowest strategy in one of the jobs
* Add minimum versions for pytest-datadir and pytest-mock
* Update uv version
