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However, that increases the chances of having outdated documentation, so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.

Validates if the input is a number.

v::number()->assert(42);
// Validation passes successfully

v::number()->assert(acos(8));
// → `NaN` must be a valid number
