[enh] engines: rework bing engine (#5793)
* [enh] engines: rework bing engine Only Bing-Web has been reworked. Some features now require JavaScript (paging and time-range results). Cookies no longer work, parameters such as `cc`, `ui`, ... alter the results. The engine only appears to use the locale from `Accept-Language` header properly. The rest of Bing's child engines (Bing-Image, Bing-Video, ...) seem to benefit from using `mkt` param in conjunction with the `Accept-Language` header override, although Bing-Web does not (?) * [enh] explicit mkt * [fix] engines: bing_videos.py https://github.com/searxng/searxng/pull/5793#pullrequestreview-3881883250
