docs: reorder incomplete features list alphabetically in command_line.rst

The --enable-incomplete-feature flag uses sorted(INCOMPLETE_FEATURES)
in mypy/main.py, so --help displays features alphabetically:
InlineTypedDict, PreciseTupleTypes, TypeForm.

The documentation listed them in a different order (PreciseTupleTypes,
InlineTypedDict, TypeForm). Reorder the option metavar and the feature
descriptions to match the alphabetical order shown by --help.

Fixes #20171
