Send captions of "document" attachments to Whatsapp rooms

[ilmaisin]

Describe the bug
Captions of "document" attachments are not send to Whatsapp rooms. Only the file attachment is sent.

To Reproduce
Send a file containing both a video and text to a Telegram room that is bridged with a WA room

Expected behavior
Both text and video should appear in the Whatsapp room

Screenshots/debug logs
If applicable, add screenshots to help explain your problem.
Use logs from running matterbridge -debug if possible.

Environment (please complete the following information):

• OS: linux

• Matterbridge version: 1.25.3-dev

• If self compiled: output of git rev-parse HEAD While I have built my matterbridge myself per these instructions, I cannot find any relevant git repository from my system.

Additional context
Image captions are sent just fine.

This file apparently has specific code to handle captions for "image" messages, but not for "document" messages.

#1652 A similar issue was fixed last year but for Discord instead of Whatsapp.
