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However, that increases the chances of having outdated documentation, so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

Alpha

Alpha()
Alpha(string ...$additionalChars)

Validates whether the input contains only alphabetic characters. This is similar to Alnum, but it does not allow numbers.

v::alpha()->assert('some name');
// → "some name" must contain only letters (a-z)

v::alpha(' ')->assert('some name');
// Validation passes successfully

v::alpha()->assert('Cedric-Fabian');
// → "Cedric-Fabian" must contain only letters (a-z)

v::alpha('-')->assert('Cedric-Fabian');
// Validation passes successfully

v::alpha('-', '\'')->assert('\'s-Gravenhage');
// Validation passes successfully

You can restrict case using the Lowercase and Uppercase validators.

v::alpha()->uppercase()->assert('example');
// → "example" must contain only uppercase letters
