Add ability to send files as attachments instead of links
Fixes: https://github.com/chatwoot/chatwoot/issues/1074
## Changes
- `emaily_reply` : We will attach the small attachments as attachments
and large ones as links
- `reply_with_summary`, `conversation_transcript`,
`reply_with_out_summary` : We will change the attachment format to the
following instead of the previous `View the attachment here`
```
Attachments:
file_name
file_name2
```
