bash --self-update

Solution
Bash does not have the ability to update itself!
Software updates on a computer are limited to a super user. But Bash can be used by everybody. It does not make much sens to put the update functionality into a program, everybody can use, although only super users are allowed to do the update. This is the status quo on Unix, where Bash came from. On Windows, which came from DOS, a single user OS, the situation may be different.
Inventing non existing and not documented command line options is unrewarding. Read Bash's manual to know, which command line options are available.
It is the work of a package manager to install software and to update software. Almost every operating system has its own package manager. Even on Windows there are at least two different package managers.
BTW: The question is off-topic here. Try it at superuser.com.
