Replace placeholder "name" with "subject"

The `{{name}}` placeholder could represent different things depending on
the state of the Result, and referring to it as `{{name}}` seems
arbitrary. This commit changes it to `{{subject}}`, which is much more
generic and it describes well what that placeholder can mean.

Length

Length(Rule $rule)

Validates the length of the given input against a given rule.

v::length(v::between(1, 5))->isValid('abc'); // true

v::length(v::greaterThan(5))->isValid('abcdef'); // true

v::length(v::lessThan(5))->isValid('abc'); // true

This rule can be used to validate the length of strings, arrays, and objects that implement the Countable interface.

v::length(v::greaterThanOrEqual(3))->isValid([1, 2, 3]); // true

v::length(v::equals(0))->isValid(new SplPriorityQueue()); // true
