Correct French validator placeholders and typo from PR #3771 review thread

[Copilot]

This updates translations/validators.fr.xlf to resolve all comments in review thread #pullrequestreview-4845798667, including the “fix all mentioned occurrences” follow-up. The issue was mismatched placeholder keys in French targets (compare_* vs compared_*) and a typo that could break interpolation consistency.

• Placeholder key alignment (compare_* → compared_*)

  • Replaced incorrect French target placeholders with Symfony-compatible keys:
    • {{compare_value}} → {{compared_value}}
    • {{compare_value_type}} → {{compared_value_type}}
  • Applied across all referenced compare-message units, including the additional multiple-of occurrence in the same file.

• French translation typo correction

  • Fixed mamaximum → maximum in the collection size message.

<!-- before -->
<target>Cette valeur doit être égale à {{compare_value}}.</target>
<target>Cette valeur doit être identique à {{compare_value_type}} {{compare_value}}.</target>

<!-- after -->
<target>Cette valeur doit être égale à {{compared_value}}.</target>
<target>Cette valeur doit être identique à {{compared_value_type}} {{compared_value}}.</target>
