+/**
+ * # Regex for translation keys
+ * This regex matches the following function calls:
+ * 1. `t("<some_key>")`,
+ * 2. `t("<some_key>", {key: "<some_string>"})`, or
+ * 3. `<Trans i18nKey="home_hero_subtitle" t={t}>`
+ *
+ * It also ensure that we don't match any other similar function calls (e.g. `format("dddd")`).
+ *
+ * ## Explanation of the regex
+ * - (?<!\w): negative lookbehind to ensure that there is no word character before "t" or "i18nKey"
+ * - (?: ... ): non-capturing group
+ *   - t: for the use of `t("..")` OR `t("..", {key: ".."})`
+ *     - \(("[^"]*"): captures a string enclosed in double quotes followed by an opening parenthesis
+ *     - (?:,\s*\{[^}]*\})?: optional non-capturing group so that we match the optional interpolation object
+ *   - i18nKey=".+"[^\w]: for the usage of `<Trans i18nKey="home_hero_subtitle" t={t}>`
+ *
+ * */
