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.

# CountryCode
- `CountryCode()`
- `CountryCode("alpha-2"|"alpha-3"|"numeric" $set)`
Validates whether the input is a country code in [ISO 3166-1][] standard.
**This rule requires [sokil/php-isocodes][] and [sokil/php-isocodes-db-only][] to be installed.**
```php
v::countryCode()->isValid('BR'); // true
v::countryCode('alpha-2')->isValid('NL'); // true
v::countryCode('alpha-3')->isValid('USA'); // true
v::countryCode('numeric')->isValid('504'); // true
```
This rule supports the three sets of country codes:
- ISO 3166-1 alpha-2: `alpha-2`
- ISO 3166-1 alpha-3: `alpha-3`
- ISO 3166-1 numeric: `numeric`
When no set is defined, the rule uses `'alpha-2'` (`CountryCode::ALPHA2`).
