website: Updated supported gcc versions
gem5 is able to compile and run with gcc version 9.3.0 on Ubuntu 20.04 LTS.
The documentation on the building page of the website was updated to
reflect the change in gcc compatibility, as it was previously
stated that gem5 worked with up to version 7 of gcc.
