What changes are proposed in this pull request?

Upgrade black to use --force-exclude option for simplifying pre-commit hook:

# Now:
# `grep -v '^mlflow/protos'` is because `--exclude` option specified in `pyproject.toml` is ignored
# when files are passed on the command line.
black --check $(echo $git_diff | grep -v '^mlflow/protos')

# With `--force-exclude`:
# We no longer need `grep -v '^mlflow/protos'`
black --check $git_diff

We no longer need to use grep -v '^mlflow/protos'.

Black 21.10b0 automatically aligns docstrings.

[BenWilson2]

this new version of black has a config that ignores all of these automatically?

[harupy]

If we specify exclude, it overwrites the default value of exclude.
If we don't, black should automatically use the default value of exclude.

If for nothing else, the docstring formatter in this new version is great!
