Update pytest fixtures

[ElliottKasoar]

Currently used fixtures are deprecated, and will be removed with AiiDA version 3, so we should look into using fixtures from aiida.tools.pytest_fixtures.

Most fixtures have a direct correspondence to aiida.manage.tests.pytest_fixtures, but currently doing this seems to result in the default profile not being set when callling verdi run.

This can be fixed along the lines of

def test_example_md(example_path, aiida_profile, janus_code):
    command = ["verdi", "profile", "set-default", f"{aiida_profile.name}"]
    result = subprocess.run(command, capture_output=True, text=True, check=False)

but it ought to be fixable via the fixtures directly.

just be careful how you split the command, passing it like that can be dangerous if not all things are correctly escaped
