MySQL docs bugs weren't really bugs

I went to report the MySQL docs issues I mentioned at https://markamery.com/ghost/#/editor/post/643564502f17df1693fb95be.

Damn, it was obnoxious that I had to create an Oracle account to do this and that they demand my address, employer, and "work phone" (WTF? I'm a programmer, not a sales rep! Most of us don't have "work phones"!) to do so. I gave them precisely the amount of data they deserved:

Anyway, when I came to write it up, I figured that I should make sure I was installing MySQL precisely the way the MySQL docs told me to. And - aha! - I wasn't. Although the MySQL docs list a way of installing with Apt, it's not an installation from the OS's default Apt repos but from an Oracle-controlled one. And when I try installing things that way, I'm prompted to enter a root account password:

The Ghost docs are still wrong (since they suggest installing from the OS's default repos which do use auth_socket) but the MySQL docs are arguably not outright wrong (although still kinda unhelpful if you stumble into them without context after running apt install mysql-server to install from Ubuntu's default repos).
