Changelog Entry

Samples

• Sample 01.getting-started/l.sharepoint-web-part, 01.getting-started/k.direct-line-token, and samples under 07.advanced-web-chat-apps is being archived and will no longer receive updates, in PR #5533, #5536, and #5537, by @compulim

Description

restify depends on some dependencies that are potentially out-of-maintenance (string_decoder@1.3.0 is having low vulnerability). Due to resources, instead of migrating it from restify to express, we are archiving the sample instead.
