option as-tree not working in command

[r4cker]

Symfony version(s) affected

6.4.4

Description

Hello,

I configured crowdin to import my translations but the as-tree is not working properly

php bin/console translation:pull crowdin --as-tree

I have to specify the following command to force the tree structure

php bin/console translation:pull loco --force --as-tree 1

How to reproduce

use the following console command

php bin/console translation:pull crowdin --as-tree

--as-tree is not taken in account

Possible Solution

I have to specify the following command to force the tree structure

php bin/console translation:pull loco --force --as-tree 1

Additional Context

in the file Symfony\Component\Translation\Command\TranslationPullCommand

The option is converted to an int

$asTree = (int) $input->getOption('as-tree');

but if the value is not an int it will not be taken in account

The implementation of translation:pull is indeed using lots of options with InputOption::VALUE_OPTIONAL without actually handling this properly (options where the value is optional are much harder to use to support them properly as you need to distinguish the case where they are not passed from the case where they are passed with no value).
Most of those options should not even use that flag but InputOption::VALUE_REQUIRED instead (for instance, passing --format without a value makes no sense).

Note that TranslationUpdateCommand suffers from the same issue about allowing --as-tree with no value but not supporting that case properly.
