Replace pytest-lazy-fixture with pytest-lazy-fixtures

[hugovk]

Replace https://github.com/TvoroG/pytest-lazy-fixture with https://github.com/dev-petrov/pytest-lazy-fixtures because the former isn't compatible with the newly-released pytest 8 and appears unmaintained.

• Raise error with pytest==8.0.0 TvoroG/pytest-lazy-fixture#65
• Compatibility with pytest=8.0.0? dev-petrov/pytest-lazy-fixtures#3
