Bump electron-installer-redhat to 0.5.0

[da2x]

Versions prior to 0.5.0 don't run update-desktop-database on post-install and post-uninstall. This causes the Brave icon to not appear in GNOME/KDE/others after installation (user must install another package or reboot) and cause it not disappear when uninstalled for the same reason.

@da2x would you mind letting us know how and what to test on this PR? thanks!

@luixxiul, build environment should install electron-installer-redhat 0.5.0 or newer. (0.5.0 is the current stable release.)

The specific change from this release that is important to Brave is the new icon installation process. To test this, if you don’t trust upstream, is to setup a new Fedora Workstation release in a virtual machine (like VirtualBox). Install the rpm file with dnf install ./brave-release.rpm. Now open the Activity menu (top left corner of GNOME), and search for Brave. Brave should be available, with icon and all, immediately without first having to log out and back in again to the system. This improves the first-install experience by making Brave available in the application dashboard immediately.
