Render audio, video and voice attachments in telegram.

Editor assessment

The subject fully describes the feature — audio, video, and voice attachments now render in the Telegram channel — and enumerates the media types so no diff is needed. Feat matches the capability addition, and the channel name in the subject compensates for the missing scope. No body appears, which is acceptable for a self-explanatory rendering addition, and the Co-authored-by trailer is properly formed. The trailing period after 'telegram' is a small hygiene blemish, as is the capitalised opening, but neither impairs comprehension. A clear, complete, publishable feature message.
