Replace isValid() calls with assert()

There's more value on showing how `assert()` displays the validation
messages than simply showing if `isValid()` returns `true` or `false`.

However, that increases the chances of having outdated documentation, so
I created a doc linter that updates the Markdown files with the
correct message.

Countable

Countable()

Validates if the input is countable, in other words, if you're allowed to use count() function on it.

v::countable()->assert([]);
// Validation passes successfully

v::countable()->assert(new ArrayObject());
// Validation passes successfully

v::countable()->assert('string');
// → "string" must be a countable value
