Localizing Admonitions

New locales can be added by creating a pull request. The pull request needs to accomplish the following:

1. Create the locale in the /src/locales/ folder by copying the en.ts file. The file should be named to match the string returned by moment.locale().
2. Create the translation by editing the value of each property.
3. Add the import in locales.ts.
4. Add the language to the localeMap variable.
