Explain how to access files from the I2P browser as root
Until #8280 is solved we should document how to access files from the I2P browser outside of the chroot.
The only way to do that would be being root and accessing /var/lib/i2p-browser/chroot/home/i2pbrowser/Downloads.
This should be added to the Known issues for 1.2.1.
