BabelNet v5

Version 5 was released on 2021-02-02, and the formatter URL (P1630) has been changed from https://babelnet.org/synset?word=bn:$1 to https://babelnet.org/synset?id=bn:$1&lang=XX, with XX being the language code, e.g., EN, https://babelnet.org/synset?id=bn:02886551n&lang=EN

However, unlike for version 4, which apparently utilized the user's browser default language settings, this URL format requires that the lang code to be predefined ― e.g., both https://babelnet.org/synset?id=bn:02886551n and https://babelnet.org/synset?id=bn:02886551n&lang= produce "Missing search language parameter".
