{#- Dynamically selects the appropriate translation key based on the provided `number` and `lang` context.
If a `number` is provided, the macro will attempt to pluralize the translation key based on the language's rules.

Parameters:
- `key`: The base key for the translation string, matching the i18n files. Example: `results` to get `zero_results`, `one_results`, `many_results`, etc.
- `number`: Optional. The numerical value associated with the key.
- `language_strings`: A dictionary containing the translation strings.
- `default`: A default string to use if no translation is found for the key.
- `replace`: Optional. If `true`, the macro will replace the `$NUMBER` placeholder in the translation string with the provided `number`.

The macro supports special pluralization rules for:
- Arabic (`ar`): Has unique forms for zero, one, two, few, and many.
- Slavic languages: Pluralization depends on the last digit of the number, with exceptions for numbers ending in 11-14.

NOTE: If the logic for pluralization is modified, it needs to be replicated on the JavaScript search.
