[bug]: Announcement API issue with repeat_msg

[danardf]

FreePBX Version

FreePBX 16 and 17

Issue Description

Using API GPL, announcement module, if repeat_msg is set for example in the request allAnnouncements, there is occured.
Indeed, repeat_msg expecting to get int() but it receives an empty string.
This item need to be empty for disable status or be set to 0, 1, 2 ......
So, if the annoucement is disabled (empty) there is a type error (string instead of int).
Even if this item receives a digit or numeric data, it needs to accept an empty data. So, it should be string anyway.

The doc doesn't exist on the wiki regarding annoucement.
It will be useful to write one.

Operating Environment

announcement - 16.0.7

The issue is present on 17 too.
