Switch to consistent shorthand hash syntax

[jandudulski]

The only thing that I don't like more than a shorthand hash syntax is mixed syntax. When standard was introducing EnforcedShorthandSyntax: either a consistent option didn't exist yet (actually either didn't exist too, it was introduced thanks to standard ❤️ ) but now it should be no brainer to switch to this one.

# with either

# good
{foo: foo, bar: bar}

# good
{foo:, bar: bar} # !!!

# good
{foo:, bar:}

# with consistent

# bad
{foo: , bar: bar}

# good
{foo:, bar:}

# bad
{foo: , bar: baz}

# good
{foo: foo, bar: baz}
