feat: Add the ability to mention team in private message (#11758)

This PR allows agents to mention entire teams in private messages using
`@team_name` syntax. When a team is mentioned, all team members with
inbox access are automatically notified. The scheme changes can be found
[here](https://github.com/chatwoot/prosemirror-schema/pull/34).
