Add automation to detect missing locales and generate translation issues

[ArtyomVancyan]

The react-phone-hooks relies on manually maintained locale files, and new languages added to antd-phone-input or mui-phone-input can be missing (e.g., enUS). So, create a script that:

1. Checks all language keys used by dependent packages.
2. Compares them against existing locale files in react-phone-hooks.
3. Automatically opens a GitHub issue, mentioning all missing locales, requesting translation entries.

This should work similarly to the existing script that keeps phone validation patterns up-to-date.
