Update yapf requirement from ==0.22.* to ==0.31.*

[dependabot]

Updates the requirements on yapf to permit the latest version.

Changelog

Sourced from yapf's changelog.

[0.31.0] 2021-03-14

Added

• Renamed 'master' brannch to 'main'.
• Add 'BLANK_LINES_BETWEEN_TOP_LEVEL_IMPORTS_AND_VARIABLES' to support setting a custom number of blank lines between top-level imports and variable definitions.
• Ignore end of line # copybara: directives when checking line length.
• Look at the 'pyproject.toml' file to see if it contains style information for YAPF.

Changed

• Do not scan exlcuded directories. Prior versions would scan an exluded folder then exclude its contents on a file by file basis. Preventing the folder being scanned is faster.

Fixed

• Exclude directories on Windows.

[0.30.0] 2020-04-23

Added

• Added SPACES_AROUND_LIST_DELIMITERS, SPACES_AROUND_DICT_DELIMITERS, and SPACES_AROUND_TUPLE_DELIMITERS to add spaces after the opening- and before the closing-delimiters for lists, dicts, and tuples.
• Adds FORCE_MULTILINE_DICT knob to ensure dictionaries always split, even when shorter than the max line length.
• New knob SPACE_INSIDE_BRACKETS to add spaces inside brackets, braces, and parentheses.
• New knob SPACES_AROUND_SUBSCRIPT_COLON to add spaces around the subscript / slice operator.

Changed

• Renamed "chromium" style to "yapf". Chromium will now use PEP-8 directly.
• CONTINUATION_ALIGN_STYLE with FIXED or VALIGN-RIGHT now works with space indentation.

Fixed

• Honor a disable directive at the end of a multiline comment.
• Don't require splitting before comments in a list when SPLIT_ALL_TOP_LEVEL_COMMA_SEPARATED_VALUES is set. The knob is meant for values, not comments, which may be associated with the current line.
• Don't over-indent a parameter list when not needed. But make sure it is properly indented so that it doesn't collide with the lines afterwards.
• Don't split between two-word comparison operators: "is not", "not in", etc.

[0.29.0] 2019-11-28

Added

• Add the --quiet flag to suppress output. The return code is 1 if there are changes, similarly to the --diff flag.
• Add the indent_closing_brackets option. This is the same as the dedent_closing_brackets option except the brackets are indented the same as the previous line.

Changed

• Collect a parameter list into a single object. This allows us to track how a parameter list is formatted, keeping state along the way. This helps when
