    git primer: Fix two errors
    
    Recommend pushing HEAD:main in the vendor branch docs, since that's
    always going to be right.
    
    Stop recommending people set push.default to 'freebsd'. It's an
    enumerated value that's not a branch name. Most likely correct value
    here is 'upstream'. However, there's enough people with asymetrical
    setups that I'm just removing the setup rather than describe all the
    special cases.
