Remove "BleachBit As Administrator": broken by default on Fedora
Upstream offers a .desktop entry (based on the inline catted PolicyKit
files here in the spec) for launching BleachBit with administrator
privileges. However, their current implementation requests the password
not for the invoking user with sudo access, but for the literal root
account -- which by default on Fedora is never actually set. Even if the
user manually sets a root password, the bleachbit-root executable only
works from the command line; the .desktop file silently launches and
then exits again without prompting for a password at all.
Unless or until the upstream developers figure out another solution
(discussed at <https://github.com/bleachbit/bleachbit/issues/950>),
I think Fedora users are better off just opening a terminal and doing
`sudo bleachbit` instead.
