AlphabeticallySortedUses disagrees with VSCode on alphabetical order of '\' and '_' characters

[joachim-n]

The coding standard wants the lines to be like this:

use Drupal\action_link\Ajax\ActionLinkMessageCommand;
use Drupal\action_link\Entity\ActionLinkInterface;
use Drupal\action_link\Plugin\ActionLinkStyle\Ajax;
use Drupal\action_link_formatter_links\DisplayBuildAlter;

But if I select them in VSCode and do 'Sort lines ascending' I get this:

use Drupal\action_link_formatter_links\DisplayBuildAlter;
use Drupal\action_link\Ajax\ActionLinkMessageCommand;
use Drupal\action_link\Entity\ActionLinkInterface;
use Drupal\action_link\Plugin\ActionLinkStyle\Ajax;

The sorting is compatible with PHPStorm. I was not able to find specification of the order between \ and _ in PSR 12. I'm ok to merge PR that will make this configurable.

I'd argue that the coding standard and PHPStorm are correct here and that VSCode is wrong. VSCode is sorting the strings as-is whereas the coding standards and PHPStorm are more aware that we're dealing with "nested sections". If we alphabetically sort words then "action_link" would come before "action_link_formatter_links".

We can see that PHP treats these as nested "paths" because the following is uncommon but valid PHP:

use Drupal\action_link\{
    Ajax\ActionLinkMessageCommand,
    Entity\ActionLinkInterface,
    Plugin\ActionLinkStyle\Ajax,
};
use Drupal\action_link_formatter_links\{
    DisplayBuildAlter,
};

We should probably file a PHP issue with VSCode instead.

Looks like there is an existing VSCode issue - https://github.com/microsoft/vscode/issues/48123

JFYI, because of different preferences in the past, in another CS, we have added configurability here: https://github.com/mayflower/mo4-coding-standard?tab=readme-ov-file#mo4formattingalphabeticalusestatements - although persoanlly especially using a locale-dependent function is a bit too much, how high is the probability that a PR, introducing the same options, gets merged here?
