/**
* Initialize translations.
*
* Call this with the path where translations are located. This function internally calls the [bindtextdomain](https://man7.org/linux/man-pages/man3/bindtextdomain.3.html) function from gettext.
*
* Translations are expected to be found at <path>/<locale>/LC_MESSAGES/<domain>.mo, where path is the directory passed as an argument to this function, locale is a locale name (e.g., en, en_GB, fr), and domain is the package name.
*
* @param domain defines the domain name e.g. name of the package.
* @param path specifies the directory as `string` or as `URL` in which gettext should search for translations.
*
* For example, assuming this is in a package called example and the default locale is configured to be French, it will load translations at runtime from ``/path/to/example/translations/fr/LC_MESSAGES/example.mo`.
*
* ```js
* import * as slint from "slint-ui";
* slint.initTranslations("example", new URL("translations/", import.meta.url));
* ````
