Symfony version(s) affected

6.*

Description

I have a application which was recently upgraded from Symfony 3.4 to 6 and I have noticed that there is a region missing from the Intl component.

The region that I have found was "AC" - https://github.com/symfony/intl/blob/3.4/Resources/data/regions/en.json#L3

Within the application, we have the following method:

public function getCountryName(): ?string
    {
        if (null === $this->country) {
            return null;
        }

        return Countries::getName($this->country);
    }

However, this now throws a Symfony\Component\Intl\Exception\MissingResourceException exception.

The only option for us is to catch this exception and return the code instead:

public function getCountryName(): ?string
    {
        if (null === $this->country) {
            return null;
        }

        try {
            return Countries::getName($this->country);
        } catch (MissingResourceException $e) {
            return $this->country;
        }
    }

It seems odd that this region has disappeared when it still exists here: https://www.iso.org/obp/ui/#iso:code:3166:AC

How to reproduce

echo \Symfony\Component\Intl\Countries::getName('AC');

Possible Solution

Load "AC" and any other missing regions back into the Intl php arrays. Unless this was intentionally removed?
