[REM] hr_recruitment: remove broadcast of new employees on hardcoded channel

This is specific and updating the content is not easy for non technical
people. As same result can be achieved with a server action based on
employee creation it has been decided to remove the broadcast, and therefore
the template and code linked to it.

This commit is linked to task ID 1843122 (and 1868112) and to PR #25295
(and #25889).
