Subject: [PATCH] Add additional metadata to post reminder (#22306)

The webapp needs to construct the full message because
the team_name needs to be inserted into the permalink.

So we need to send everything in the metadata for the
client to construct the message.

Also, we set a custom post type for the client to easily
add a custom condition.

```release-note
NONE
```
