Fix evaluate-cli import error with huggingface-hub 1.0.0

[tonycoder-hub]

Fixes the remaining huggingface_hub>=1.0.0 incompatibility reported in huggingface#712.

Background

The HfFolder crash from the original report was already fixed by huggingface#701 and shipped in 0.4.6, but main is still not importable end-to-end under huggingface-hub>=1.0.0. huggingface_hub removed the git-based Repository class in v1.0.0, and src/evaluate/commands/evaluate_cli.py imports it at module scope:

>>> import evaluate.commands.evaluate_cli
ImportError: cannot import name 'Repository' from 'huggingface_hub'

So the evaluate-cli console script fails to start on any recent huggingface_hub.

Changes

• src/evaluate/commands/evaluate_cli.py: drop the Repository import and replace repo.git_add() / git_commit() / git_push() with the same plain-git subprocess call that already clones the Space, factored out into a small run_git helper. This keeps the local checkout, the auth model, and the printed instructions exactly as they were, and works on both huggingface-hub 0.x and 1.x.
• setup.py: raise the huggingface-hub floor from >=0.7.0 to >=0.10.0, the first release that ships huggingface_hub.utils.build_hf_headers (used in evaluate/utils/file_utils.py). No upper bound is needed now that the code works with 1.x.
• setup.py: add cookiecutter to TESTS_REQUIRE so the CLI module can be imported by the test suite (it is otherwise only in the template extra, which CI does not install).
• tests/test_evaluate_cli.py: new regression test.

Tests

The new test deletes huggingface_hub.Repository before importing the CLI, so it reproduces the 1.0.0 failure regardless of which huggingface_hub version is installed, and it pins down the git command sequence used to push the generated template.

python -m pytest tests/test_evaluate_cli.py tests/test_file_utils.py tests/test_hub.py tests/test_load.py tests/test_metric.py tests/test_save.py -q

• Before the fix: tests/test_evaluate_cli.py errors with ImportError: cannot import name 'Repository' from 'huggingface_hub'.
• After the fix: 49 passed, 2 skipped.

black, isort and flake8 are clean on the changed files (the pre-existing flake8 warnings in module.py, file_utils.py and logging.py are untouched).

Out of scope

.github/hub/push_evaluations_to_hub.py also uses Repository, but that CI script is already covered by the open PR huggingface#732, so it is left alone here.
