In v12, the hr module did not have a hard dependency on mail_bot, so the
users could uninstall it if they did not want/need its functionality. In
v13, mail_bot was added as a dependency to include the notification
widget and the odoobot state in the user forms modified by the hr
module. However, this also brings potentially unwanted functionality to
anyone who installs an hr related application.
This commit removes the dependency on mail_bot by adding the mail_bot_hr
bridge module, which provides integration between mail_bot and hr if
both modules are installed.
